I recently loaded up a bunch of 230 grain FMJ round nose (Winchester bullets) 45 rounds using 5.5 grains of Unique powder and all was great in my Dan Wesson Heritage.
I switched only the bullet to a 230 grain copper plated (not jacketed) round nose made by Rainier and the gun will not cycle completely. The first round that I jack in will go in fine, but all the rest end up with a dent in the nose. Everything is exactly the same as when I made the FMJ bullets. Same powder, measurements, etc.
A guy at the range told me maybe to try more powder - that the new bullets maybe needed more kick to get the thing to cycle all the way, and it seemed to make sense. I loaded some at 5.7 grains and the problem was worse!
The crazy thing is I want to get to doing straight lead round nose bullets, but at this rate, I'll never get there. Any ideas as to what is going wrong?
