Hi, I am new to this forum and I just joined a few minutes ago so I could help with your problem...if I could. You solved your problem and I did read the list of posts and your final response that you figured out how deep to set your bullets and eliminate feeding problems.

I just started loading 45 ACP for my Hi Point. (I got it to see if I like the caliber in a semi auto pistol and am planning to get another (more than one 45) if like it)). I loaded some heavy 45s for my Ruger Blackhawk and when I tried to chamber rounds in the HP they failed to feed, and failed to chamber because of the seating depth. I pulled a lot of bullets and did some experimenting and finally settled on 1.243" OAL and all problems went away. My bullets are Suters Choice Bullets and I buy them locally, but I prefer Missouri Bullets. I just needed them now so I got them locally.

I found what I believe is a reason for the hang-ups...exposed lead. Once the amount of exposed lead was minimized which allowed the case brass to contact the feed ramp instead of the lead, all problems went byebye. I think it is just that the harder metal of the case slides up the ramp easier than lead and with a chunk of lead sticking up above the case mouth the cartridge snagged on the ramp.

I also found that after stuffing the bullet down a bit farther, using Lee's 4th die of the set, the Crimp/Post Size Die squeezed the area of lead outside the case mouth down to the diameter that the case mouth gets crimped.

Now, a question: Anyone who can please field this: I see repeated mentions about crimp size or diameter etc...is this just a mic measurement at the end of the case mouth where the case is crimped?

Thanks for the good info. I will go to the check in station now and intro myself.
