[QUOTE="SHRTSHTR, post: 332012, member: 12514"] Hi, I had a custom 338 Lapua built a couple months ago and have seen pressure signs using 90.0grns H1000 powder. Ejector marks on case are very noticable. A little bit about the rifle, Stiller Tac338 Action, 28" Lilja Barrel 1-10 Twist. Velocity is 2723 average. Bullets are seated to magazine length (Badger M5 BM) It has been suggested to me by someone on this site, that I might have a headspace problem. I ordered Headspace gauges from PG&T. Sure enough the go gauge goes but so does the no go gauge. The no go gauge was not an easy closing of bolt but it was not hard to close either. Can someone tell me how much pessure should be used when trying the no go gauge? Once again, I did not force the no go gauge. When I tried closing the bolt it started to cam over pretty easy and when finishing the closing of the bolt it was a little stiffer. I plan on using .001 brass shims to measure exactly what my headspace is. Look forward to hearing your suggestions. [/QUOTE]
