all loads were chronoed with a magnetospeed. I don't get stiff bolt openings, extractor swipes, or flattening of primers. I can fire 10 rounds in 90 seconds and reach up and grab the barrel and it isn't hot. I put the barrel on in January and I already have 800 rounds on it. Based on the loads presented does anybody have any idea how many rounds I can go before it would start to open up on me. I'm shooting PRS and it's my first season and I'm worried I'm not going to make it to October. I've been averaging a little over 2000 rounds a summer fucking around so I figured I would be good but I did the math yesterday and realized I was at 800. Thoughts?
