I'm looking for a 6.5PRC load that will get 2900+ F/S with a 127 gr. Barnes LRX bullet from a 20 inch barrel. I would appreciate first-hand experience answers rather than conjecture. Thanks.
H4831SC gave me the highest velocity in my 24" barrel. Might be hard to get there with a 20". This is load data I got from Cutting Edge for their 125 Lzr.
I have a load using 54.5 gr RL 26 and 120ttsx, Peterson brass. Load is pretty mild, just a quick one I threw together and it put 5 under 1/2”. Just under 2900 out of a 20” barrel. I imagine 55 grains or so would get you to 2900 depending on brass
