[QUOTE="bamban, post: 3070472, member: 17722"] Thank you for sharing. Early on I cut the crown at straight 90. Just burnish the sharp edge of the crown. We experienced early degradation of precision. What I found the sharp 90 crown was so brittle that showed crown damage. I re-crowned the suspect barrel with a chamfer. Precision was restored. Back in 2009 I sent out all metal parts for my M1A hunting and defense rifle, except the receiver. The place do not have FFL, still don't. Over 200 rounds in testing rifle had failure to fire. Extracted the round, chambered another, same problem. Found out the tip of the firing just sheared off. Meloniting went through and through making the tip so brittle. Replaced firing pin with non treated and fired a few more hundreds, no issue. Rifle is truck gun when I hunted by the TexMex border, thus the reason I wanted to make sure it went bang. [/QUOTE]
