“Mostly good! Running these in my Sig Sauer P220. About 1 out of 10 bullets I have a failure to go into to battery due to the bullet design. It gets hung up when it feeds from the magazine and the top of the bullet hit the barrel chamber. I've never had this happen with standard round ball. They also don't sest very deep in the case since they are shorter than the 230gr. I had a couple that wanted to seat a little weird. In terms of how they shot, I have them loaded with Ram Silhouette a little below max and they are wicked fun! Loud with a flash. Deadly accurate load. Cycle the action perfectly aside from the occasional battery failure. My intentions are to continue shooting 185gr, but I think I'm going go switch the the hollow base round nose next time.”
