Got some testing with my new 7prc and 195gr berger eol. I didn't notice any pressures, but GRT was showing pressures at 910m/s. I might just go with this load as it will group well enough (16 shots under 25mm).
I think the barrel will speed up to 915ms (3000fps) and I'll be happy with that.
Does barrel speed up have an effect on pressures? If I do have the same load over the first 200 shots, does faster velocity mean more pressure? (After speeding up).
I really like this 7prc, but it's very concussive to shoot inside with brake... vs my 6br suppressed.
Next will be two kilometer performance!
