[QUOTE="Kroberts, post: 1165710, member: 71507"] I think I put this in the correct section. But I'm curious whether this issue could be the factory ammo or the barrel. I've got a cz527 22 hornet that I could only find hornady varmint express ammo for. I finally ordered some PPU stuff from midway that doesn't have the problems I've had with the hornady. Initially I though I must have a very large chamber in tr rifle since when fired the hornady brass is swelled out in front of the case web, has flattened primers, and I could only get one or two loadings before the primer pockets wouldbt hold a primer, and about 1 in 10 would blow a pocket on factory firing. I've only fired about half a box of the ppu but it hasn't had any of those issues yet, though I havnt reloaded any of it yet to see how long it lasts. But the primers are nice and round, no blowouts so far, and no swollen cases. So do you think that lot of hornady is loaded too hot, is just too hot in my rifle. Or is my rifles chamber large causing issues? I'm not complaining about hornady, I usually don't shoot factory ammo, but I love their billets and like their brass. I'm just curious if it's worth having my chamber cast, I'll probably do it anyway. The hornady ammo shoots better groups than the PPU does. After bedding the rifle it does 1moa vs the 2moa the ppu does I do need to make a chamber casting and check the bore diameter. Thanks, Kyle [/QUOTE]
