Basically ALL the cheap bulk pack 115 grain 9mm out there these days. Rem, UMC, Blazer Brass, Blazer Alum and WWB are known widely to be underpowered and won't run in some guns like H&K.A real 9mm? What's an unreal 9m then?
I used to buy S&B 10MM 180 Gr FMJ to feed my G29; it was only ;like $15 per box, fairly hot stuff and always ran great.
S&B is cheap, but I've never heard them talked about being weak. All of it that I've shot bears that out too. I think that's what he was talking about being "unreal" 9mm.
