I cast my Lee 358-200-RF gas check bullets out of WW+2% Tin. They dropped at about .362”. I powder coated and then added gas check and sized .359 which gave me .358”-.3585”. I loaded a number of rounds and then tried to chamber them in one of my Remington model 141’s. The bolt would not lock and I had to force the slide to eject the round. The bullet showed Engagement with the rifling. But the nose is supposed to be smaller than what got sized. Any ideas what I did wrong? See pics.
Is my PC too thick maybe?
Actually one of my 141’s would lock into battery, but difficult to eject and showed rifling engagement.
