[QUOTE="just_jon, post: 1991540, member: 112153"] I tried the 123 AH with some faster powders in my 26” 6.5 CM T/C Encore. I loaded six rounds at .3 grain intervals ending at Quickload "near max" load for my specs. Results as follows: IMR 3031: 3,031 fps @ 39.2 grains with no pressure signs. Blown primer @ 39.5 grains (3,052 fps). QL showed pressure of 61,700 for 39.5. RL10X: 3,056 fps @ 35.0 grains with no pressure signs. Varget: 3,022 fps @ 41.5 grains with no pressure signs. CFE223: 3,178 fps @ 44.9 grains with no pressure signs. Blown primer @ 45.2 grains (3,208 fps). QL pressure for 45.5 grains was 58,883. RL15: 3,174 fps @ 41.9 gr with no pressure signs. Blown primer @ 42.2 grain (3,205 fps). QL pressure - 60,365. CFE223 and RL15 produced 200 fps speed bump with no pressure over the 130 Berger and 131 HH. I used QL to estimate max as published load data is not widely available for some of these powders with this bullet weight range. I recognize that I was pushing and in one case (RL 15) exceeded published book data, but none were indicated by QL to exceed SAAMI pressure for this round. My goal was to find pressure and I found it. I just did not expect to find it this way. Reading pressure can be problematic with the Encore, but I typically get minor primer cratering or flattening when I'm getting near max, but that was not the case today, I will shooting groups with CFE223 (44.9) and RL15 (41.9) tomorrow.
