338 Edge Pressure Signs
I have a question for all you Edge guys. I finally finished my Edge build, and am very excited about the potential of this weapon. I have begun my normal barrel break-in routine of 1 shot clean, 1 shot, clean for about 20 rounds, and then 3 shots, clean for another 15 rounds. I'm using Rem 300 UM brass, Federal mag primers, 92 grns of H-1000 with the 300 SMK. COAL 3.77, which is all my Wyatt’s box mag will hold. The problem is, about every 5 or 6 shots, I completely flatten a primer and crack a case. What's the deal with that? From scanning this site, religiously, I concluded that 92 grns of H-1000 should be fine with the 300 SMK, but it seems to be "too hot" for my rig. Maybe I have a defective batch of brass. Do any of you guys have any suggestions?
Thanks in advance.
