Okay here goes, I came across a pretty good deal last month on 1000 30 caliber 210 grain Sierra match kings. Previously I had loaded 190 grain custom competitions and reloader 22. I typically use the OCW method when developing a load. Using reloader 22 with the match kings I started at 56.0 grains and went up to 59 grains and half grain increments. The 56.0 and 56.5 shot a well-rounded group, I started experiencing pressure signs at 57.0 grains and it went away at 58.5. I was getting slight ejector marks on the case head but once I stepped up to 58.5 and 59 the ejector marks went away. Not once did I experience sticky bolt lift or cratering primers or flat primers. The 59.0 loads tightened up really well and was rounded but shifted to the right some.
Yesterday I went to reload these cases( they were virgin) and noticed the primer pockets were seriously loose so I pitched them. The charges that I loaded up yesterday are the 59.0 but I decided to Moly the bullets in order to lower the pressure. I'm hoping with Moly I can save the brass to at least a couple of firings. Has anyone ever seen pressure signs like this before? For what it's worth I'm shooting a custom .30-06 with a tight necked Ombermyer chamber.
