[QUOTE="Bart B, post: 609216, member: 5302"] I've heard this before. Never worked. And it varies with firing pin strength. Popping a primed case without bullet and powder results in a deeper dent than a live round with normal pressures. Get a gage to measure primer protrusion, then measure it with a micrometer or caliper. For near full shrouded bolt faces (Rem 7XX and post '64 push feed Win. 70, for example) use a depth micrometer/caliper with the bolt removed. Or, with a brass rod equal to barrel length, use a depth micrometer/caliper to measure firing pin protrusion from the bolt face. [/QUOTE]
