I can only fit 15, but I think even if I could get 16 in it, I would probably still only load 15. My American Eagle rounds come in a line of 5, so loading 15 just makes more sense to me, plus I have OCD.
I just picked up some more 147 grain flat nose ammo. It's hard to find it in America Eagle, thankfully, there's an app were you can browse hundreds of companies that have ammo in stock.
I've always been told to stay away from cheap bullets like Wolf and Tulammo. I'm currently using American Eagle 124 grain FMJ, and Winchester 115 grain FMJ. No problems with either of these two.
I guess what I mean by dirty is, more cleaning was needed even from shooting say 100 Tulammo versus 200 American Eagle. I've never used it, I'm just going by what a buddy of mine told me.
