Man I love the Cortina screw ups more than any other Gun Tube. Jareds Guns&gadgets, Demo Ranch, Reno May, F Class John, Winning in the Wind, West Desert. Eagle Eye, Sooth, Hickock45, Warrior Poet Soc, 22 Plinsker. Maranda's Armed scholar. Johnnies Reloading Bench. Brian Kleckner. MAC, and many more. ( man I don't have a life) but thank you all.
I absolutely can't believe the difference from such a small amount of recoil management change. It blows my mind that such little changes have such an impact
@@doomfathertm8771 i wouldn't be surprised if it's both, but I do think the recoil is a big factor. Bryan Litz has a nice slow mo video of the muzzle of a rifle moving rearwards before the bullet exits. add some lube, now the rifle can move more than before. harmonics probably factor in when considering a lubed recoil is less friction.
Very impressive process, Erik. As Karl Popper said, “Science is basically trial and error” and Socrates, “The unexamined life is not worth living”. The utter heartbreak of making a mistake and the great joy of discovering why makes life worth living. Thanks for sharing.
Dang! Being an engineer, and looking at failures, that was a brilliant test!!! I was watching the match as time allowed and was bummed that the third day took you down. I bet that won't happen again. Best of luck next year.
So, are we seeing a shirt depicting a large shot group with " I lube my stock forend" soon? Just joking, love your videos. Amazing what seemingly trivial things might influence precision in top tier competitions.
Amazing that something that seems so inoculous could cause such a difference! Kudos for the determination to figure it out and the mental fortitude to recall the details. Lessons learned!
Thank you for sharing this. I know it can be difficult to share these kinds of mistakes but it helps us all. Thank you for your dedication to the sport.
Mr. Eric i checked this video and i could not believe that a a bit of grease can do this but yet there it is!!! Just want to say a huge amount of respect from here thank you for sharing such great knoledge and hard work with us. Since ive watched your videos my reloading went cheaper my gun started shooting extremely well. So thank you sir. And dont worry the next nationals youll smoke the competetiin your a fenominal shooter. Take care
Eric, I certainly understand being frustrated with not performing at your absolute best at a competition, but you should be so stoked that you have so much knowledge that you could have actually analyzed the problem and figured it out. That in itself is amazing and I really believe you should be incredibly pleased with yourself that you were able to figure it out to be able to analyze that and be consistent enough of a shooter to realize the problem. Testing it back at home is incredible. You made a mistake but you're so good at what you do. You were able to figure it out and teach us all something. You are really an amazing shooter . don't feel too much frustration with that little mistake. You are human. Thank you for what you are doing for the gun community. You're shooting knowledge is greatly appreciated . Keep um small.
Thank you for this video. I never miss since I installed my E.C. Tuner Brake but if I ever do it will not be because I greased my rifle or rest. I'm sorry it was such a costly mistake for you but watching is a very cheap lesson for me I will not forget. Keeping them centered and Kind Regards, Tony
And those of us shooting long range with cheap bipods wonder why we can't hit anything. This is eye openning. Glad to know it was not the barrel. My varmint rifles both go through 1000+ rounds each season and usually get cleaned once mid season when I miss a few chucks. I can usually see carbon buildup on the crown when I miss shots. Good job.
I shot with a 40X in college. The range sergeant claimed my rifle fell out of the rifle safe and broke the front sight mount. The rifle was never the same after that, but I had no recourse for a new barrel and front sight. Now Remington's Custom Shop is a faint shadow of it's former self, so I'm going to have to follow you and F-Class John into the fully custom rifles.
Sorry eric to say but watching your videos you talk and for the right reasons about consistency but you proof to us and i believe to your self that changing something from what you practise in something diferent in a competition does matters.very good video.
Consistency = Accuracy! Lol. it’s not a cliche! bravo mr cortina for sharing. U are a protectionist and this realization, I know, stings! U could have kept it private! I’m glad u didn’t.
I new it wasn’t the dirty barrel. The only way a dirty barrel could’ve hurt you is if the fouling sped up the mv’s taking the load out of tune. The way you derive the loads in your rifle I wouldn’t expect a rise in mv to take you out of the node. Interesting content!! This is why I love the science of accurate and precise rifles. It’s the little things that can make a huge difference. A great experiment is to keep shooting a accurate rifle and not clean the barrel, except clean the chamber so a carbon ring doesn’t form, and analyze the outcome. It can be so against the grain to do this but it can and usually is very eye opening.
@@ErikCortina It was just my honest opinion, nothing else. I wasn’t trying to be a know it all guy. From what I’ve seen over lots of different barrels, it’s hard to loose very much accuracy from a dirty barrel. Especially if the round count is under a few hundred shots. The only way to know this is to go hundreds of rounds without cleaning and analyze if there’s a degradation in precision
I am guessing the recoil is not pushing back evenly........its kicking a bit sideways at the butt when you fire......making the rest more "slippery" has allowed it the push back further, allowing that extra push at the Butt to move sideways even more than normal, hence the wider group.
That's amazing that something you would think would improve consistency actually introduces variation. Really great content as always Erik. Really unfortunate that it impacted your competition. Best of luck on your next shoot.
You know it kind of makes perfect sense, you developed your load with out the grease on the bag so your groups were based on a certain amount of friction between the stock and the rest. Then when you add the grease the co-efficient of friction changes and you wind up with a slight change in the harmonic response of the rifle and in this case the group opened up. That little change made a big difference. Great video!
There was a comment on this thread about the Mantrix. Using the Mantrix might be an easy way to check for torque variation. I use the Mantrix for pistols and never thought of using it on rifles, since it picks up only 2D variations. Would be perfect for measuring the torque on the barrel. Seems like a great idea.
This should emphasize just how important consistent recoil management’s actually is. Everything U do behind the boom stick has to be the same every time! All the time. Change=change
I think most people probably don't understand the rifle is actually starting to move (backwards in recoil) the moment the bullet starts to move. It's physics. So consistent recoil control is essential for tight groups. Little things go a long way, they say...
It's amazing such a small change could cause that much deviation, thanks for finding me just one more variable to consider :) Quick, someone design a tool to measure recoil friction !
At a 1,000 yards even the smallest changes make a big difference. With long range shooting half of your accuracy is the rifle and the other half is the shooter. With the shooter, repetitive muscle memory will give you consistency. Therefore with everything the same on your rifle the only variable would be the weather. Great video, enjoyed your troubleshooting process.
It's hard to believe that a thin film of grease on the tip of the forearm could make such a difference. There are so many variables in shooting I'm surprised anybody can shoot consistently good groups at longer ranges.
Me planning a competition: "I am going to check the gun shoots and then do nothing about it, it is good to go." Me, a week before competition: "The rifle, scope and suppressor have been completely cleaned and everything possible has been tampered with, I am off to rezero the rifle and see if it still shoots the same"
The only time I clean my barrel is when the groups start opening up but it's normally a bunch of rounds before that happens and when it does I clean it and shoot several rounds through it to foul it back up a little again... 10 cents of grease that's pretty freaking crazy it xouod change something.... Great video as always keepem coming brother!!!
@@ErikCortina Yeah I guess I said that wrong but what I was getting at is all my guns shoot worse after I clean my barrel... But I don't shoot competitively and when I shoot long range it's just shooting steel between 400-1200 yards... LOL All I'm wanting to do is hear the ring I'm not shooting itty-bitty groups at 1000 yards so I get what you're saying also. It's extremely interesting and impressive to see what you guys can do with a rifle it really is amazing brother!!!
Sorry about what happened. But it shows, you don't learn from history, you learn from reflecting upon history. Thanks for sharing. Glad you found the problem.
Hi Erik, if the lubrication on your rifle affected your groups you will need to torque the screws on your rest. A tighter or loser fit on your rifle will affect your groups as well.
The Lesson? Never change ANYTHING at a match. Not even your laundry detergent. :) In seriousness, I would LOVE to hear your technical breakdown of your guess at why this caused the groups to open up. I have a couple suspicions, but like you I NEVER would have guessed it...
Hi Eric. I just watched this very interesting post. Could it possibly be that some grease found its way into your chamber by means of the chamber flag you inserted after greasing the action? Best regards from South Africa
Although the grease is a suspect I don't think you have done enough testing to verify that theory. I wonder if the real culprit is the adjustment of the force on the forearm rest. Maybe it felt the same as without the grease but the grease altered the feel and the force was actually different than normal. I don't shoot competitively anymore, largely because I got tired of fixing problem A while problem B was getting worse. I once set a Colorado state benchrest record on Saturday and on Sunday placed 20th with the same rifle with group sizes that were 50% bigger due to a brand new problem I did not have on Saturday. It is an interesting issue you had but I prefer to watch you sort it out rather than do it myself. Great shooting in any event.
Change in recoil must have changed harmonics enough to take you out of your sweet spot / node. Wonder if you could tune it while greased and get back to consistent shooting.
What a bummer Eric, just goes to show that there’s always more to learn as with anything in life. The important thing is to never give up, but learn new things and move forward. BTW, what type of cartridge “caliber” were you shooting? That sure is a bad ass looking rifle and scope combo. ✌️😎👍
I'm guessing it changed the way the rifle moved back under recoil and at 1,000 yds even tiny differences in recoil pattern will make a big difference. I don't know what the material is in the part of the rest that actually touches the forearm but some materials become sticky when grease is applied especially if the grease has and additive to make it stay put. Or it could've been the over way and made it slide easier but I think increased drag would effect the rifle more than less would. It will be interesting to see what Erik comes up with I'm betting he won't let this go until he knows for sure.
Pretty new to the channel as well as the different set ups and classes. But what's the tape or whatever that is on the barrel. I was guessing to keep the reflection off. But i was just curious
I've never participated or even seen a competitive shoot. I'm amazed that little bit of grease on the fore stock made that much difference. It was more than I would have thought. I wonder if it was rising in the rest?
For barrel cleaning it would be perfect if you could have a method of cleaning the barrel that wouldn't strip it back to perfect brand new condition, but rather back to the perfect fouled stage for best groups. So if your barrel takes 12 shots for example to foul it properly for the tightest groups, then clean it back to the 12 fouling shots. Basically if you fire 60 rounds you would then erase the particles from the last the last 48 rounds, so each time you're finished cleaning you'd be left with a 12 fouled barrel to start off with your tightest group. Of course each barrel being different it would only work for THAT barrel. When you replace the barrel you got to find the "fouled sweet spot" again. For that to work you'd at least have to know how many shots to perfectly foul the barrel for the tightest groups.
That's very interesting Erik. My mind goes to railguns that slide pretty easily and shoot extremely accurate. I would think you'd want it to slide easily, not roughly, in the rest, shoulder pressure being the resistance. Would load development with a greased rest change your groups?
The proof is in the pudding. But I just don't understand the actual physics of why greace on the forehead would change your grouping. It's just amazing to think that you're shooting technique, reloading variables, environmental conditions, are so spot on and without variation that a little bit of grease is what makes a difference. Might as well call it the butterfly effect.
Before this video, how many of you would have guess grease would have caused that much variance? 🤔
Nope!
nope
So did the grease allows the gun to jump upwards out of the rest ever so slightly?
I would never have suspected such a small thing would make so large an impact.
I've noticed a lot of the shooters are older than you. This just goes in the experience toolbox of things not to do in the future. When you're that age, the experience will make you untouchable
That's why I love watching "the Cortina". Honesty from start to end. Respect, Erik and thanks for the aftermath.
The precision required in this 1000 yard grouping boggles my mind.
So true. I am fascinated by long range precision shooting, but so far Eric’s worst group at 1050 yards looks about like my best at 100.
Absolutely.
Very impressed with the dedication to finding the error of your last day at Nationals. Respect
Lesson learned: Never introduce a new variable (grease) and expect the same results. Tough break, Erik, but at least you solved the dilemma.
Man I love the Cortina screw ups more than any other Gun Tube. Jareds Guns&gadgets, Demo Ranch, Reno May, F Class John, Winning in the Wind, West Desert.

As Paul Harvey would have said, "and now you know the rest of the story" as you know Erik the hard lessons learn are the ones you'll not make twice. 👍
I absolutely can't believe the difference from such a small amount of recoil management change. It blows my mind that such little changes have such an impact
I don't believe
its not the recoil but the barrel harmonics

"The difference between science and messing around, is writing stuff down"
Next time use Crisco. It'll glide so smooth that it'll turn your 4" group into 1". If it fails you can always fry up some chicken.
Dang! Being an engineer, and looking at failures, that was a brilliant test!!! I was watching the match as time allowed and was bummed that the third day took you down. I bet that won't happen again. Best of luck next year.
Damn your accuracy is phenomenal. 4 inch group at 1000 is impressive.
Not accuracy, precision!!!

F class is a new phenomenon to many of us..5 shot strings measuring just over 1an inch at 1,000 yards. Shall we redefine m.o.a.?
Hi Erik, if the lubrication on your rifle affected your groups you will need to torque the screws on your rest. A tighter or loser fit on your rifle will affect your groups as well.
Insane to think that made that much of a difference! Well, now ya know. Better shooting next time.
What target camera are you using?
Well, Erik, you changed your shooting setup, and it changed the gun!
The Lesson? Never change ANYTHING at a match. Not even your laundry detergent. :)
In seriousness, I would LOVE to hear your technical breakdown of your guess at why this caused the groups to open up. I have a couple suspicions, but like you I NEVER would have guessed it...
Dang I'd of never guessed that.
Was it also the variable of the different tension in the front rest?
I reckon by having the grease it's introducing very little muzzle jump
Hi Eric. I just watched this very interesting post. Could it possibly be that some grease found its way into your chamber by means of the chamber flag you inserted after greasing the action? Best regards from South Africa
Thanks for keeping it real, Erik. Now come to Alabama and build me a Barndo... and teach me shoot.

What equipment do you use to see the target hits in real time like that?
what caliber rifle is that?it's a beautiful gun!
Change in recoil must have changed harmonics enough to take you out of your sweet spot / node. Wonder if you could tune it while greased and get back to consistent shooting.
What a bummer Eric, just goes to show that there’s always more to learn as with anything in life. The important thing is to never give up, but learn new things and move forward. BTW, what type of cartridge “caliber” were you shooting? That sure is a bad ass looking rifle and scope combo.
✌️😎👍
Also what brand are the earmuffs you are using? Cheers
Nice after action. Erik try furniture polish when you clean your stock.
Any idea why the grease on the stock made such an impact?
I'm guessing it changed the way the rifle moved back under recoil and at 1,000 yds even tiny differences in recoil pattern will make a big difference.

Pretty new to the channel as well as the different set ups and classes. But what's the tape or whatever that is on the barrel. I was guessing to keep the reflection off. But i was just curious

What is your opinion on fireforming brass
I've never participated or even seen a competitive shoot. I'm amazed that little bit of grease on the fore stock made that much difference. It was more than I would have thought. I wonder if it was rising in the rest?
Hey Erik I would love to build a gun for out to 500 yards any suggestions on what caliber?? Thank you for any input!!
For barrel cleaning it would be perfect if you could have a method of cleaning the barrel that wouldn't strip it back to perfect brand new condition, but rather back to the perfect fouled stage for best groups.
