[QUOTE="chesspunker, post: 1461652, member: 106356"] I just got this email from Barnes so I'm changing my tactics. Once I get to 3200 FPS I'm going to stop and then do my ladder test from there. I no longer care about 3300 FPS. The Email begins below: [B]Sorry about the phones, we have been slammed today. Your velocities are pretty close to what they should be, probably max out at about 3200 with H4831SC powder, you will get about 55-60 fps more with the 145 gr over the 150 gr. So you can go up a little. .5 gr, increments are fine but are small increments for a case capacity this high. You are not going to go from no pressure signs to damaging your gun in .5 grains of powder. Wby is using proprietary powders and duplex loads, so don’t compare your loads to their ammunition. H4831 SC and RL 22 are different powders and should be treated as such, just because one gets a certain velocity does not mean the other will do it safely. 3300 fps is about what I would expect from RL 22 with a 145 gr. bullet at max charge. But I would expect to get about 3200 fps at max charge with H4831 SC.[/B] [/QUOTE]
