I don't know if anyone has had this experience. I started out loading 230 grain LRN with Bullseye 4.5 gr to 5.2 gr 5 rounds each. I found 4.7 seemed about best. Ran a bunch of these. Decided to try 50 rounds at 4.5 grains. They functioned ok, for maybe 25 rounds. I started to get failure to go into battery. I thought it was either the head spacing (I was spacing on the bullet, not the case) or the lighter charge.

When I disassembled the firearm (Springfield Mil-Spec) I found lead back in the chamber. My belief is that the low pressure load (light charge combined with longer than normal COAL) was not forcing the case to seal the chamber and was allowing molten lead to blow back around the case into the chamber.

I'd be interested if anyone else has had a similar problem.
