My .45 acp handloads are spitting junk out of my 1911 ejection port I cant tell if its' copper from the bullet jackets or un-burnt powder. I switched from Hodgon HP-38 to IMR PB. I use winchester large pistol primers. Before the switch I stopped crimping thinking my crimp was to tight. It doesnt happen as bad when I use expensive bullets but most bulk copper jacket bullets do it and I dont notice it at all with rainer lead safe bullets. Can anyone help? The one thing I notice is a little more than usual copper fouling in and around the slide. Is it my powder? Do I need more pressure to create a more efficient burn? Suggestions????
