[QUOTE="Texis, post: 3071217, member: 121376"] I use a caliber diameter mandrel.. ie .284, .308 etc. run it through the brass, the brass will pop back .001-2. Start a bullet in it, put it in the rifle and use the bolt to seat it into jam. Extract it and measure accurately with an ojive bushings. I typically do 3 for each bullet type. Rarely are they off by more than a couple of thousands. This method has been excellent for me for years… very accurate “to jam” measurement. Lube the ojive where it will contact the lans. Goods luck [/QUOTE]
