- Time to test the 243 Precision Load Development we worked up. I was very happy with the 95 gr Berger bullets we ran. Got the group size dialed in. Now the next step is to get the speeds and work up the Ballistic charts using Ballistic AE.

Thanks again for watching, please share this video if you enjoyed it.
I've just started shooting my 243 so far she likes the 100 and 95 grain ammo all factory ammunition I was able to get 1st shot hits on targets out to 550 yards with the 95 grain ammo
My best .243 group at 100 yards was with a Stevens 200 Factory coutour, no accutrigger,, Tasco 3X9X32, using Hornady Custom 75 gr. flat based hollow points. from homemade sandbags. 3 shot group (only usually shoot three shot groups) Inside a dime, or .457 center to center. Caliper measurement was more like .38 inches since they were inside the dime---placed on top of the group covering three shots . Not bragging, cause I never shot one like that again with probably the cheapest rig ever. I don't know what powder Hornady used in that load, but it was a good one. :)
Great presentations! It was good to see all the steps shown and explained. Keep the videos coming!
I just started loading the Berger’s in a rem 700 for 243 . 95 grain also . Unfortunately , mag wouldn’t take rounds on the lands or even up to .040 off . Found a sweet spot .065 off lands . Thanks for sharing your videos
tHANKS FOR TALKING ABOUT TWIST RATE FOR THE DIFFERENT .243 BULLETS.
Great video and learned that there is much more to reloading than what i thought. Love the set up, and the video edit. Looking forward to more videos
Tried the 105s vld in a cva hunter and it was about a 13in group and 100 yards. 1:10 won’t shoot the 105s for sure but the 75gr vmax is a laser in the same gun. I tried everything to get a 100 yard hunting group and wasted 100 bullets and days. At least they are gone now lol.
My best with the 95 grain Berger hunting VLD is 1/4 MOA using BR2 primers, Lapua brass, 42 grains of 4350. 0.001 off the lands.
Thank you for taking the time to make such an awesome and informative video. I will also be reloading the 95gr vld in my .243 once I’m setup.
No problem. Once you load that up, let me know how it shoots and what your shooting it out of.
Ha...kinda funny cause I'm headed up to MO in a few days to visit Sierra Bullets, , first time finally. Started loading in early 70's in San Jose when Sierra came out with the Spitzer Boat Tail in the 308. Plan on going around the corner to visit Star Line Brass after Sierra. I recently picked up a ROSSI 243, sweet. Must say I was surprised of light recoil. Looking forward to working with the 243, good info and important points brought out on the reloading and testing. (Subscribing)
Great video like how you give all minor reloading tips most others miss keep it coming
Hi partner. I really enjoy your straight forward no nonsense approach. I'm making a prediction that the .243 caliber is going to be the next hot thing in long range shooting....if not the .243 then the 6mm bullet is going to be the new hot trend. Obviously not new to you or me, but currently I am hearing the 6mm range of cartridges is gaining major momentum in the competition shooting world. A .243 with a fast twist and a long throat so you can load long is going to be the ticket for those high BC bullets like the bergers you've got. Tight groups. Its obvious you are passionate about what your doing.
Chad Harzbarger thanks for the comment.! I'm thinking very hard about building this new rifle in to the .243 Ackley Improved. Bullets are the same but case life is greatly extended and the speeds are much faster. I haven't decided 100% just yet, but I'm leaning that way.!
Chad Harzbarger For sure the 243 and 6 mm beats larger calibers like 308 and even 300 Win Mag at longer ranges. That’s why i shoot 243. Believe me i beat them all and they don’t really like it. For me this was the best choice for accuracy at long range. Regards from France!!! (Yep, we also have guns here).... 😎🇫🇷🎯🇫🇷😇
Vaughn Precision Your barrel life will be very short Dude! To much speed will kill it just the time to say it...
Great Video!
Love the channel try .150 off the lands I shoot Berger’s 130vld .150 off land shoots around .250 7mm 180 berger .150 off lands .360 at 100 meters 3inch group at 730m 140 berger 6.5 .150 off lands .320 at 100m , they do like to jump try it out think you’ll like it haven’t changed my load or distance to lands in around 500 rounds still shoots good 👍
Good stuff!
Here's one for anyone, 240 weatherby, IMR4350 48gr.sierra, 85gr. HPBT#1530. OAL 3.070
Works very well🐗
Thank you for sharing your expertise... what does on the lands mean? I assume you are referring to the lands of the rifling within the bore. How do I measure that n a particular barrel?
Dont just seat the bullets to the lands but make the vld 15 thou longer for a jam, they love it
In my 40 years of reloading for the .243 I"ll say for almost certainty that with rare exception most loads should be pushed up to the lands of the barrel. Actually...that holds true for most high power rifles. This holds true for my .223(600 yd single fed match round only) .280, .270 and .308. My Garand is the only one which likes the 168 Sierra backed off a couple thou...but I'm only shooting it 200yds.
Nice video series. What barell do you have on that gun?
NorthMissFish thanks, I have a Shilen barrel on most all my guns
Heated the barrel up a little much also
95gr berger classic hunters work great in a 1:10.
I got a 6mm Remington which should dido all these loads
What kind of chamber does the gun have? If it's a SAAMI spec (regular factory) chamber, then it's probably .005" or .006" oversize, so neck turning will generally be a waste of time - unless it has a tighter bench rest chamber. With SAAMI chambers, I've found that using regular resizing and seating dies usually produces the same accuracy. Because by neck turning you're taking even more brass off the case neck, (an extra .001" or .002"), thus allowing the bullet to wobble even more, not less. Having said that, I've found exceptions. I've had a number of 300 Remington Model 700 Rem Ultra Mags, with custom barrels (but with SAAMI chambers) where the accuracy was improved by outside neck turning.
However, with the Weatherby calibers, I found neck turning made no difference at all, especially with their relatively long free bore. I've also spent a lot of time getting the run out of my hand loads down to .002" or so. Nevertheless, the groups were no better than those with rounds having several times the run out. Interestingly, a long time ago, I measured the run out of a box of Federal Gold medal 308 match ammo with 175 grain Sierra bullets on my RCBS Case Master. Their run out was all over the place. But again, unless you've got a match grade chamber, it probably won't make much difference.
You need to have 4 or 5 groups of each load for statistical reliability. One group of each load won't be reliable. As well, when using Norma cases, or any cases of different manufacture, one has to take that into consideration when using reloading data. Even primer brands can make a significant pressure difference. Some Norma cases, such as their 300 Win Mags and their Weatherby cases that are also made by other manufacturers (e.g., 7 mm Wby, 300 Wby, 30-378 Wby), are 20 or 30 grains lighter. Thus that will also have a significant effect on loading data. For example, I used to make 375 H&H hand loads from 300 Wby and 340 Wby Norma brass because they would hold an extra 3 grains of powder over the Winchester cases and give me 50-75 fps more velocity FOR SOME BULLETS.
So, as they say, when hand loading without a chronograph, you only think you know what you are doing. If I were spending all that time and money on load development, I'd want a better scope than a SWFA Super Sniper. Not that there's anything wrong with them, but I'd want something that would have a higher level of quality control, just in case of parallax problems etc.
It's a tight chamber, this was a special order from Shilen. I hope to get a SB PMII scope one of these days. But the cost for me to build a bunch of rifles doesn't leave much cash to buy high dollar scopes unfortunately. I think when I build my 6.5x47 Lapua I'll top it with some nice glass since that will be my new PRS Rifle.
It's up to you but, in addition to measuring fired case heads for high pressure signs, I've always chronographed my hand loads (I almost never use factory ammo) and saved them in a dedicated notebook. It doesn't take much more time and the additional info is so helpful. Among the custom barrels I've had only one was a Shilen - for a 270 Weatherby Mag. chambered on a rebarreled Remington 700. It had the standard .378" Weatherby free bore for that caliber, but still shot .6 MOA at 200 yards with 150 grain Nosler Partitions. The IMR handout for IMR 7828 showed 73.5 grains gave 3,280 fps @ 54,100 cup. (I was careful to use Norma cases, not the much heavier, reformed Remington brass.) Actually, I went 1/2 grain more to 74.0 grains and averaged 3,263 fps. So having a chronograph told me everything was behaving pretty much as it should - as I moved up 1 grain at a time, every 5 shots. (That load exceeded the load in the Nosler manual; however, I knew from experience that the Nosler data was old and very conservative. Or maybe they used a Lilja barrel with less free bore. Whatever, to be safe, I called up Mike Harris at Nosler to discuss the data discrepancy before proceeding. Firing a number of groups for statistical validity, I also noticed that the groups with another bullet shrank when I switched from a Bushnell Elite 4-16x 50mm to a Leupold Mark IV 3.5 -10 x 40mm.
When starting out, I've had cheap scopes give me mediocre groups. Trouble is, if parallax errors are mild, you won't notice a whole lot of difference in group size and may think it's the gun. I know that SWFA scopes are highly regarded, but it's always followed by the qualification "for the price." If they're selling a scope for $299, chances are that it cost less than $30 (or so) to make in the Orient. So what kind of quality control will you get for $30? I know binoculars quite well, and you can't get decent binoculars for less than $1,000 US (i.e., Zeiss Conquest). You don't have to spend that much on a scope, but I think scopes like a Leupold Vari X-III or a Bushnell Elite 4500 would be the least that I would accept if I was spending a lot of time and money on load development. In fact, it makes sense to spend more on the scope than on the gun. I put a Zeiss Diavari 3-12x56 mm on my Remington 700. After all, even mediocre barrels will shoot MOA these days, however, the same can't necessarily be said for the repeatability, accuracy and durability of cheap rifle scopes.
Have you loaded the Barnes 85 gr tsx in your .243?
ftb427 no, I haven’t
@@vaughnprecision thank you for your response. Being as I am in California we have to shoot lead free bullets. Have a nice day.
Hello Vaughn Precision,can u tell us how many grains of poweder you use for #5
How many thousands of the rifling best group I thought that is was all about
Not sure why a 95 grain would require a 1:8 in a 243 other than bullet design. Bearing surface of only 1/3 the bullet's length explains it for me. What powder were you using?
I think I was using Hybrid-100V if I remember correctly
The factory 243 1in10 or 1 in 9 Barrel rate of twist will work best with 90 grain or lighter as a general guideline. The 100 grain loads are randomly marginally stabile.
...if you're shooting 5, measure 5...I don't think excluding "I might have pulled this one" helps you with really accurate data analysis...
So this was just a standard 243... not AI?
What model of Savage are you shooting here..?
You stated that you found the 87gn Vmax "super accurate". I've got a few questions, what was your powder and load and did you jam or jump them??
thx
lexee50 I seat them to book specs most the time. I’ve used many powders to push them H-414, H-4831sc etc. they all are accurate it seems like with that bullet.
Did you try Varget?? If so, was it better or worse??
thx
lexee50 haven’t tried any Varget in this yet.
Hey is the 243 trustworthy and does it have range?
It’s got both
Did the barrel warm up much????. thanks a lot.. SC Navy vet...
Tony Smith no, the bull barrel stays cool as long as I’m giving it a rest about every 10 shots.
what if the last two groups you shot didn't have any wind they might just be a buttonhole you should shoot them over without wind
Was that range you were at up by Bellingham?
Nope, in south Olympia area
Buddy you forgot to mention which COL was the best shot group om your loads.
Frank Crisostomo the loads there were .010 off the lands shot the best. This is a common theme with the 243 ELD bullets
What Rifle are you shooting for this load?
Vicki Lee that’s a Savage model 12-FV with a Shilen 1-8 twist ratchet rifle barrel
Hey great series. I’ve noticed a lot of people who shoot for extreme accuracy don’t use the magazine, why is that?
Jake Birkmaier usually you’ll need to get the bullets touching the lands. This often makes the length to long to feed in a mag. So they shoot them single shot
Vaughn Precision thanks for that, I thought that the magazine somehow decreased accuracy. You’re a great channel Who deserves more subs and views. I try to like all of your videos I watch.
Jake Birkmaier thank you..! Appreciate all the views and likes. Maybe someday we’ll hit 10,000 subs.! That’s my goal..!
