I have 2 24/47's that measure 323 when slugged, I use a Lee 175gr boolit and size them to 325. I tried paper patch using transparent paper rapped twice the diameter. When I measure again I read 330 inch (paper and boolit). Is this to big to shoot safely?? At 1700-1800fps, maybe 2000fps or even 2400-2600fps. I'm trying to develop a replacement for J-boolits and heard paper patch will get me there. I get very good results without the paper patch at .325 inch using gas check and 860, 5010 or H4895 powder.
