    The primers from my .308 were BR2s and not the ones I used with my .260. I'm using two different lots of CCI200s in the .260. So I have seen cratering with one lot of BR2s and one lot of CCI200s with a mild load. When I look at the crater under a magnifying lens it looks die cut. You can see...

    AI AX260 - Pierced Primer

    Fired 40 rounds with 42gr H4350 and no pierced primers. I did get one cratered primer which makes me nervous.

    Folks, I fired 40 rounds of the 42gr load without a pierced primer. I shot the rounds with two lots of primers. The old lot had one cratered primer. The new lot looked just fine. I believe I'm good for Scott's class. I decided to take a look at some of my fired .308 brass and I could see...

    Exactly - and that's why I need to stand back and see the big picture. At least for the matches at UNC, I'll hardly see a difference. Brass and barrel life should also increase. For now I just need a bomb proof load that will make the steel go "bang". I need to focus on my shooting skills...

    That is correct - I started load development with the new barrel. This is the first time I've shot a .260 in my life. Have always been a .308 / .223 / .30-06 guy.

    Hi Anton, I have a CED M2 chrono but thanks for the offer. My loads with 43.2gr H4350 averaged 2805fps with 4 fps SD. I shot out at the 600 yard range at Cascade the other day and when I true up my ballistics I get 2850fps. I'm using virgin Lapua brass of the same lot and I always keep them...

    Yes - I'm running a .260. I've made up some loads at the lower accuracy node (42gr H4350) and will be testing today.

    I'll need to find somebody with a bore scope then. Anybody out there with one? I'm happy to drive over.

    Considering the barrel is a Bartlein and chambered by Dave Tooley for AI North America I would think everything is in spec - so I would agree that a problem with the barrel is far fetched. What would you look for/measure to determine if there is a problem with the barrel?

    In response to Bigwheels and Known: - I am .030 off the lands - Load is not compressed at all...plenty of room left in the case - I have a Redding micrometer seating die. I don't check every round but I do check periodically. Ed

    Firing pin is nice and smooth. I will also try a different lot of primers. Since I'm loading ammo for Scott's training class on the 26 & 27 I'm going to back down as I don't want to get distracted with pierced primers.

    I've always heard CCI are the hardest with the thickest cups.

    Blowing out at the firing pin dent - looks like you drilled a hole in the primer. I had 300 rounds total through a new barrel before the problem started. After a thorough cleaning, including the throat, I still pierce every 15 rounds or so. This was a new batch of virgin Lapua brass...

    Hey Kevin, I appreciate the kind offer but I've got some Federals already. Thanks though...

    Hi, They are blowing out at the firing pin. Looks like you drilled a hole in them. Ed

    Folks, I'd like to tap the collective wisdom of the Puget Sound group to help me with an issue. I'm starting to pierce primers with 43.2grm H4350 and 139 Scenars. I'm using Lapua brass and CCI #200 primers. Suspecting carbon and copper fouling, I cleaned the bore thoroughly. I threw...

    AI AX260 - Pierced Primer

    Hi, Since my earlier post I even used some Butch's Bore Shine and ran a phosphor bronze brush up and down my bore approx 60 times. I did get some carbon but no blue to indicate copper. I fired about 15 shots and I got a pierced primer. I am now going to start loading one accuracy node lower...

    AI AX260 - Pierced Primer

    I cleaned my barrel with Sweet's 7.62 - the strongest stuff I had sitting around. I didn't get any copper at all - nada...zilch. At least I got all the carbon out. I'll shoot tomorrow and see how I do. If I continue to get pierced primers I will work up a load at a lower accuracy node...

    Any improvement after all that work? Are you still blowing primers? I don't hear of anybody piercing primers with the .308 and they are running some hot loads.

    AI AX260 - Pierced Primer

    So after 300 rounds my AIAW with a .260 Bartlein started blowing primers. At first I saw some of the cratered primers that Ring has pictured not quite understanding what was about to happen. I'm shooting CCI 200 primers, Lapua Brass, 43.2gr H4350 with 139 Scenars. I am .030 off the lands...
