Yeaaaaahhhhhh......
On their website. If that ruger is a 1 moa gun - itd not be hard to score hits that far.
Berger's stability calculator is pretty slick - by the way. With a 1 in 10" at sea level - "marginally stable" with a 175 and 10 twist.
Twist Rate Stability Calculator
Our newly updated Twist Rate Stability Calculator not only tells you what your SG is, but it also lets you know if you are reaching your optimized BC.bergerbullets.com
Notice I said "consistently".
Ultra long range shooters are finding that the "marginal" twist rates are doing better when the bullet goes subsonic.
Bryan Litz mentions this in one of his Applied Ballistics videos.
I thought I remembered a thread over where the shooters are accurate about reloading the 7PRC.
Speeds are all over the place.
With different powders and barrel lengths and makes.
Seems as far as Hornady factory ammo is concerned, people are noticing that the early ammo shoots faster than the newer ammo.
Possibly the shortage of RL26. That's the theory anyways.
People also noticing that the Proof Research barrels are shooting faster.
Personally, IF I were to do a 7PRC, it would be the 7PRCW.
