So last hunting season, I was hunting on a family owned piece of property and had heard there was a black bear wondering around at times. I thought no big deal, I'll never see it anyway. But one morning as I was sitting up at the top of a rock ledge overlooking the local watering hole, and here come...

Ah, okay... That makes sense. The brass was "over-inserted" at the longer length because the datum line wasn't long enough. I'll have to cut some more brass and set the sizer die up 0.010-0.015 and see if that will chamber. That way my neck length inst longer, but the overall brass is. I t...

Well, I spent some time this weekend working on the issue. Tried to take Dellet's advice. Made some minty fresh brash to 1.375 and set the sizer die up .005" with a feeler gauge. Rifle didn't want to chamber that, so set the sizer die all the way down, and pushed the shoulder back to normal spe...

The one bullet I pulled did not appear to have any damage to the jacket. I'm hoping to find time this weekend to load up some ...

The firearms is a built AR with a 10.5in 1/8 twist FN CHF barrel that PSA sells. Has a lantac EBCG, SilencerCo ASR muzzle brake, and keyholed with both the SilencerCo Omega ...

Alright guys, I'm new here so bear with me. I went to the range this weekend and shot some handloads I hadn't used much before. They were 110gr Vmax loads. I noticed every round was keyholing at 7-10 yards. So without anything else to shoot besides Barnes rounds, I loaded a few up. Also 110gr handlo...
