The 14.9 seem to dirty up my cyclinder and barrel. The primers I used were standard Remington small pp. recoil was manageable but didn't seem as accurate but was in a hurry and was 19 degrees out. Can't wait to move to SC. My cylinder was really dirty. I did back off crimp because of hard extracting. Do you guys trim once fired brass. Got a trimmer but I miked a few and they were the same as my factory cases. I think I am missing something these are federal silver cases. ( nickle plated I was told they were good to reload for 9mm so did with the 357. Cases are also dirty. I have 50 ready to be loaded with Same Remington primers any suggestion.
