I was out of town today, when my Lee 225 gr mold showed up, and my CH dies and shell holder. I am all set to fireform some brass if I can get everything together by Saturday. I have some questions, has anyone shot the 225 gr without a gas check? How about Powder coated? I dont have any gas checks yet, but some are on the way. I also have several hundred GC .324-180 gr 8mm cast bullets with lube grooves. I did not slug the barrel, but it looks mint. I stuck one of the slugs in the muzzle, and the grooves engaged the slug on the round nose, not even close to the driving bands. I think they would be alright for fireforming and shooting in general, I know they are not under bore. Also, what Unique charge should I use in fireforming, 13 grs or so.
