Thanks Frank glad to see you joined up!I'm going to tell you....you best be careful with these over bore capacity type rounds and the 6.5PRC is a classic example of one. If you don't keep up with the cleaning and you let the barrel get away from you....I'm going to guarantee you that you will have problems! I had two guys back in February....neither guy cleaned the gun. One guy for 280 or so rounds fired thru it. Took bore scope pictures of it and called and complained about the accuracy falling off and that he thought it was bad steel from the erosion/wear that he was seeing.
For one....he wasn't seeing erosion. Most people when they look down the bore they don't know what they are looking at. What he was seeing was the amount of carbon build up. I got him to clean the rifle and I told him how to do it because of how bad it was by letting it go the way he did for 280 rounds! So to my surprise he cleaned it and took it to a PRS match that next weekend. He said accuracy came right back and he won all of the long range portion of the match as well. Longest distances he shot was 1250 yards. Was over all match winner.
I've seen too many guys already putting 120ish round thru the gun in one day and they have a two day match to shoot and they will not clean the gun that night before the next day. Then they wonder why they're having issues.
I'll also say this....I've seen shooters as well as ammo makers let the 6.5PRC barrels get away from them and they've wrecked the barrels in as little as 400+ rounds. Take care of them and they can go around 800-900 rounds in 6.5PRC.
I will also say this....in calibers where you have over bore capacity cartridges vs. bore size....the carbon can keep building up and for one cause accuracy issues and another even though it's rare it can happen but you can blow up the gun. Not our barrel but last October a shooter put 1000 rounds thru a 338 Lapua and didn't clean it for even a single round. The gun came a part. Shooter wasn't harmed. By not cleaning it....the bore will tighten up/restrict especially at the throat of the chamber area. There could've been other issues with the barrel itself that compounded the problem but I do know that not cleaning it isn't going to help anything either.

I've learned a LOT from you on the Hide, you saved me from ruining a barrel that I was about to brush up with Iosso bore paste.
@slowelk
if sample size of one isn't enough for you then you'd be wise to take Mr Greens advice..
He knows more about barrels than all of us on this forum combined
