Midway Prvi Partizan .308 - Edge Cracks?

[aermotor]

I just ordered some boxes of of .308 from Midway: http://www.midwayusa.com/eproductpag...29954#enalarge

Some of the edges where the bullets are placed are rough and look/feel like they have small cracks around the rim. Is this stuff reloaded? Is this normal? Just seemed strange, but I dunno.

I've never noticed that on any of mine. I've run through quite a bit of both the 168 and 175 grain stuff, both seemed to be assembled pretty well. With current demand though, they may have slipped a bit on the quality control due to increased production.

I'm not a reloader or ammo expert in any way, but I just checked the ammo that I got from Midway and I think you're talking about their crimp? Looks that they put that crimp on their Match ammo as it doesn't appear on the 145 gr FMJ "white box" ammo?

Not 100% sure if the crimp is suppose to help with accuracy, perhaps a reloader can chime in on that? But I don't think it's anything to worry about. I checked some old 62 gr. FMJ Winchester ammo (USA223R3) that I have and it has the same kind of crimp, albeit its more nicely executed.

total newb here, but I believe crimp increases pressure, which would boost velocity.

The crimp might look unsightly, but the ammo works just fine. Shot a box of the stuff out of my Savage 10 FP over the weekend and it worked pretty well. The groups weren't spectacular, but I can live with it. Here's one of the better 5-shot 100 yard groups that I got using this stuff.
