Re: 7mm reload problems (ballistics)
I'm running 65gr of R22 with 162gr Interlocks, CCI 250 primer, and Winchester or R-P brass. We've shot these from Parker Hale 1200 Super bolt and a BAR. Not pressure issues in either.
Between the 7mm Mag, 270 Win, and 270 WSM my Nosler book and chrony are far apart. But the .223 loads have been pretty close, as well as 45 ACP. I am not sure if their data is way off or there is much play in the magnums. I know the 7mm Mag data has been the same for past 3 editions for R22.
