I've been working up some loads for my P45 and have been having some difficulty with many rounds getting caught up in the barrel/not fully going into battery and causing the slide to freeze shut. With this I carefully place the slide on a bench and forcefully press down to eject the round. I'm using 200gr Missouri .452 lead hi-tec bullets with an OAL of 1.255," crimped to .468, over 5.5gr of Win 231. Dies are RCBS with a Redding taper crimp die. The dimensions match Blazer Brass rounds that function just fine. The only variable is likely to be significant in that with the plunk test my round sits just a bit higher that the Blazer rounds. What adjustment to I make to cause the bullet to sit deeper with the plunk test? Thanks.
