Please do a video of your slugs compared to a pellet of the same weight. The same air gun setting. Same distance. And please comment on how much you needed to adjust scope. I bet you will be surprised by the results. 👍🏼
yeah that will be a good video i noticed substantial differences between the 2 calibers when it comes to heavy slugs. the LW barrels do a good job up to about 50gn then the BC starts to fall off. for example the 50gn RBT in this video had a BC of .191 a 72gn RBT had a much lower BC at .143. now in my custom Green mountain .257 barrel its a different story the 72gn RBT have a BC of over .225 at 930 fps and 132 FPE. i'm waiting on a custom 22 cal barrel designed for a 55-65gn slug i just need to send to the gun smith
I ordered and recieved I believe the 46gr BTHP from you and i must say, they are impressive looking. However, with my Armada dead-nuts bulleye at 55 yrds, these slugs are all over the map. I have a Vortex Diamondback Tactical 6-24x50 sitting on top of it. Can't seem to figure out whats going on. Thought maybe my scope was off, but switching back to pellets....nope. Spot on POA/POI. Have you or anyone else had any issues like this? I want to figure this out....Thanks
I would try single loading them if possible and see if the accuracy improves some magazines dont like baot tails. It could also be that the prob doesnt push them forward past the transfer port. Have you used other slugs like flat base or cup base? If none of that seems to be an issue then its possible your barrel favors .249 over 250. Hopefully that will help a little bit. Let me know if you any other questions
It probably doable but it not worth it for the benefit. The tips take a long time to put in and in .177 there is not much benefit. In the bigger calibers is much easier to do and there is greater increase in BC. We haven't listed any ballistic tips yet because of the cost it takes to make them. We have been playing around in .250 with them because that's the smallest caliber that showed a good performance increase in BC. I'll see if I can find your orders so I find your address I'd be happy to send you some stuff to help with your testing.
@@airgunsofidaho4886 ok just make you send a message or email with your order so we know it's you and we will send you extra stuff to tryout to help with your testing I think we mite have a few t-shirts left also 😉.
To a point kinda, it has to do with weight and length heavy slugs get longer the weight increases the sectional density wich will increase the BC. But if the slug gets to long for the barrels twist rate the BC will not be as good as it can be. The .257 vs 250 will demonstrate that very well in the really heavy slugs. For example in .250 a 65gn RBT had a bc of .156 wich is lower then the 50gn RBT at .191 where as in .257 a 65gn has a BC of .225. This is due to the 250 having a 1/17.7" twist rate compared to a 1/14" twist in a standard 257 barrel. Hope you enjoyed the video
@@griffinairgunammo7518 The video was great learn a few new things about slugs. Have you noticed any difference between shooting slugs at under 950 fps vs 1000 plus. I guess 900 fps is where subsonic starts.
@@griffinairgunammo7518 I was trying to calculate the BC of some slugs. I was shooting the 21gn nsa in.177. I was get a velocity of 985 at the muzzle and 835 at 100 yards. And just messing around with the chairgun app. I discovered that when I changed the G1 to the G7 or G8 the b.c. when down. Do you think the boat teil slugs need more speed or are they not long inoff for the .177 cal. Or maybe the spin twist is too slow.
@@airgunsofidaho4886 you are correct the transonic zone is from 900-1300 fps basically this range of velocity is where the air flow around a projectile can accelerate to supersonic speeds. The result of that is small shock waves can form over the surface of the slug causing the slug to loose stability. This normally referred to in the mach scale mach 1 being the speed of sound, 900 fps is mach .08 as you get closer to mach 1.00 the turbulence and intensity of the micro shock waves will get more intense the closer you get to mach 1. Once you get to mach 1 the micro shock waves coalesce into 1 large shock wave at the nose of the slug as the slug itself passes the speed of sound.
@@airgunsofidaho4886 chair gun is not that great check out stryloc ballistic app it is much more comprehensive. It's also much more accurate for calculating BC. The drag model for flat based slugs is G1 or RA4 boat tails are in between a g1 and G7 the dont quite have a long enough ogive for a true G7 profile. Chair gun doesnt give me the right solution for G7 it says it's less efficient then g1 which is totally wrong. It also doesn't show gyroscopic stability values like streloc does this can be very helpful when trying to find the right slug. By putting in weight and length and twist rates it will tell you how stable that slug will be before you buy it

Hey Ben, that moderator is amazingly quiet; nice.

My Condors have always liked the Boat tails. Twist rates would be an interesting video.

Hello, what is the twist rate of your condors and which barrels are they? Thanks

I have been single loading them. Although out of curiosity i wanted to see if they fit my mag and they do. But my testing was done by single loading.
Data charts? … Power Wheel settings?
Can you guys put ballistic tips on .177 slugs.
It probably doable but it not worth it for the benefit. The tips take a long time to put in and in .177 there is not much benefit. In the bigger calibers is much easier to do and there is greater increase in BC. We haven't listed any ballistic tips yet because of the cost it takes to make them.

@@leadslinger5130 awesome. Give me a few days and all make an order.
