105gr berger VLD

[Greg Duerr]

Does anyone have any experiance using the 105gr VLD? I was wondering if a .243 AI with a 1x9 would be able to stabalize that bullet or would you HAVE to go to a 1x8? What kind of velocity are you getting out of your 105's in a .243 AI

I have been using them in a 6mm-06 with a 1-8 twist with great results i have pushing them at around 3250 just a guess as i havent chronographed them yet. But my brother is shooting a 243AI with the 105's and a factory 1-9 twist barrel recut to AI and they stablilze just fine.

I have tried them in a factory 1x10 twist with ok results. The 95 grainers shot 1/2 MOA so stuck with those. You may have a bit more luck with the 1 in 9. Let us know how it turns out.

I use the 105 gr. VLD's in my .243. It has a 1-in-8 twist barrel that seems to stabilize them just fine. I'm pushing them right at 3,000 fps. With the higher velocity provided by the AI version, I would think your 1-in-9 twist barrel should stabilize them just fine.

I just did some load development this week for my brothers new 243AI. It has a 1-7.5 twist. I tried 4831sc and h1000 in Lapua brass, CCI-BR2 primers Berger 105vlds 26 inch barrel. End up getting 3315fps with 48g H1000. Dropped down to 47.3 3275fps. Fire-formed with 40g 4831sc 105 Amax. Shoot out at 1020 yards yesterday. Had a five inch 6 shoot group. Here is his 4 shot group from 100 yards. H1000 47.5 and 47.3

Someone gave me this equation a while back. It is called the Greenhill Formula. Out of curiosity, I have done the math on a few of my rifles with the bullets that shoot well and it does work as long as one allows for some wiggle room.





where:

• C = 150 (use 180 for muzzle velocities higher than 2,800 f/s)
• D = bullet's diameter in inches
• L = bullet's length in inches
• SG = bullet's specific gravity (10.9 for lead-core bullets, which cancels out the second half of the equation)

My 243AI wears a Rock Creek 1-9"tw at 24". It shoots the 105VLD very well. I'm running them at 3200 with 44gr of R-17 in Lapua brass. I also moly them.
