I've been testing out lead bullets in my 10MM 1911. I found they work great, I found they are accurate and I found I have very little if any leading. All good. My question is about switching over from lead to jacketed in the same range session. I is OK to switch from lead to jacketed without removing whatever minor lead deposits I may have left in the barrel? What about switching from jacketed to lead? Any reason I should not do this without cleaning?
