I went to the range and opened a new box of Remington (UMC) .40S&W to be fired from my G27. I started with Federal .40, but only had 20 rounds of it. It went off great. Then I shot this UMC stuff... the paper didn't have a nice little hole. It 'ripped' the paper and made like a 1/2" to 1" ripped hole. The ammo was tumbling. I've never experienced this, but had heard about it. The guy next to me was shooting a G23, and he shot a few of these rounds with the same result. I paid $80 for this box!! I'm pissed. Think it's worth calling Remington? Anyone else ever get this? I shot about 30 rounds of it and have 220 left. Now I feel this ammo is virtually worthless. Strangely though, the holes were 'accurate'. It flies straight for the 7 yards I was shooting, but i'm sure the accuracy decreases as distance gets greater with a tumbling bullet. Thoughts?
