[QUOTE="buckbrush, post: 901719, member: 13680"] I spoke with a barrel maker a while ago that sends a lot of barrels for nitride treatment. He stated that they should be lapped very vigorously after the treatment and before shooting. He stated that if you don't feel like you are hurting the barrel, you aren't doing it enough. JB Bore Paste and minimum 1/2 hour. This may not be your problem..just a thought. I've also had weird results with Alliant powders when nearing max pressure...which it sounds like you are very close to. RL15 and my 35 Whelen IMP got very scary very fast. A 1/2 grain jump in powder above slight primer cratering resulted in a face full of gas and the primer in the mag box. Good luck. I hope you get it worked out and post the results. I have a barrel going out for nitride treatement soon. [/QUOTE]
