To answer your question, my shooting partner and I went with the 375 Snipe Tac and the 375VM2 with the mindset of having an extremely accurate long range caliber. We have both shot the 338LM for years at the extended ranges and wanted to push to the next level. We focus more so on the challenge in long range accuracy then who has a bigger gun.
The 375 Snipe Tac, we chambered and built ourselves - 32" 9 twist
We finished it late fall 2015
We ran the 350 SMK up to 3200 fps with good accuracy, and we also are running the GS414s at 2850 fps in which the accuracy has been floating in the 1/3 to 1/4 moa at 600 yards. Both are conservative loads without any pressure signs.
I know 600 yards is not much but at least it's good enough for load development, then this spring we can stretch things out to 2400 yards again.
The 375VM2 was built by Dave Viers and as stated he has retired from building rifles. This rifle being a 36" 9 twist and his Viersco Action {not a Barker or Lawton} is a very well put together and balanced rifle. We are looking foward to getting this out at to 2400 this spring as well.
This rifle was chambered for running the GS414s at 3400fps +/-
I do have a 36" 16-8 gain twist to run as well someday as well.
I'm looking forward to shooting and testing more with the 375VM2 when the weather and my work schedule allows here soon.
Cheers
