I am currently at the range working up a load for my 300wm. I'm using 180gr AB's over RL-22. This is a continuation of my previous load work up, but just changed seating depth. I started at 73.7, 74.0, 74.2, 74.5, 74.7, and 75.0. My question is has anyone ever seen velocity drop off by going up .2gr? 73.7 gave me an average of 3016fps, up to 74.5 gave me an average of 3060fps with no sticky bolt or over pressure signs. I just shot 74.7, but it dropped off to 3020fps AV, ES 7, and SD 4. Seems odd that velocity dropped
