45 colt case bulge

I’m getting .008” bulge near the rim on my 1894. thats vs sized brass. I’m using starline nickel brass. Measuring the full length of the brass this is pretty consistent. I’m 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 I’ve been using therefore I personally don’t feel good about using that as a reference.

Any input is appreciated.

Whats your load?

I "THINK" a slight bulge may be common as the sizing die does not reach all the way down the case.

Yes the bulge is there from the sizing die.
