I recently bought the new Lyman Devastator mold in .44 cal and went to the range today to work up a load. The bullets are weighing 275 grains and I loaded them in half grain increments from 18 to 22 grains of 2400. I got one ragged hole shooting the 21.5 grain load and this was the tightest group of all fired but. . . as I was approaching this load I noticed that some of the bullets were coming out of the brass from recoil I guess and the base pin was coming out of the cylinder. I put the base pin back in, fired a couple rounds and it came out again. The bullets were all crimped as tight as I could get them. I ran the press up and then screwed the seater die down until it touched the ram and when I crimped the bullets I ran the brass all the way into the die. I don't think there is any way to crimp them any tighter. My question is what do I do now? How do I keep the base pin in place when firing. What can I do about the bullets coming out the front end of the brass. Is this load too hot or do I have some other problems?
