Iím getting .008Ē bulge near the rim on my 1894. thats vs sized brass. Iím using starline nickel brass. Measuring the full length of the brass this is pretty consistent. Iím wondering if this chamber is too loose for stout loads. Absolutely no trouble extracting or ejection but I did slightly flatten the cci 350 Large pistol magnum primers. This is my first time to use the cci 350s. I know they are tougher than the WLP Iíve been using therefore I personally donít feel good about using that as a reference.
