[QUOTE="MagnumManiac, post: 1556799, member: 10755"] The most common problem is a chamber larger than .513” above the belt. Forget headspace, the belt takes care of that and CANNOT be changed. Measure as best you can, a vernier that measures to 1/2 thou will tell you the diameter at the expansion line/web juncture. If it is above .513”, you have a chamber issue. Period. In some instances, it is not a chamber issue but a die issue. I have several dies in 264WM, body dies, FL Dies, neck dies and bushing dies, one set I have, a Redding Deluxe 3 die set, WILL NOT size so a fired case goes back in unless I put feeler gauges (.008”-.010”) under the case head, with the expander wound up so it doesn’t dent the feeler gauge. My chamber measures .002” over SAAMI minimum, Redding’s body die just sizes the shoulder to fired dimensions, so it too is a little large. Funny thing, in my match chambers, all dies I have will bump .004” with hard cam over. Cheers. [/QUOTE]
