[QUOTE="Ingwe, post: 1076737, member: 35101"] Maybe you are going crazy, but if you are I am as well. When working up my load here is what I found: 7mmRemMag 26" Benchmark Barrel 1:9 twist with 168gr Accubond Lr's With 79.5gr of RL-33 I got a 10 shot average of 3,114fps With 79.3gr of RL-33 I got a 10 shot average of 3,128fps The accuracy was pretty much the same and with the lower charge the high-low spread was within 50fps so I decided to go with it. I hope that someone here comes up with a good explanation for it as well since this always bugged me! [/QUOTE]
