I can't put 100 through. I just have this box. Shooting 30 without a problem is good enough for me I guess. I was planning on one magazine, actually. It's a 50-box. $21.99 I think. Reliable ignitionwise I was thinking, was my question. I don't like the idea of +p for reasons of excessive wear. The cavity looks interestingly wide, unlike golden saber. Yes, it's a hornady bullet in a nickel cartridge. It seems a tad weak at 310 tf/lbs. 375 would have been nicer.
