[QUOTE="megalomaniac, post: 5859004, member: 2805"] My cousin thinks when I do seating depth testing, I may actually find pressure drops some with increased jump. Will watch for a drop in pressure along with a drop in velocity. If that happens, I may be able to work powder charge back up from that seating depth. I think there's about another 1.5g powder capacity left in the case unfilled with the book max But so far, not really impressed with the 7prc... I got lucky with a fast bbl in my 7mmWSM... getting 3350 fps from the 140s out of a 25in bbl. (Was getting 3400 without pressure, but I backed off a tad to save bbl life) [/QUOTE]
