I am in a shooting league at my local range. We shoot 10 rounds at 10 targets for a total of 100 rounds. So I normally by my Win white box at wall mart. But they have been out the last two weeks. So I by my box at the range today. Start shooting an not all that bad. Start loading my 3rd clip. That is when the round I picked up did not look right nor feel right. Yep was not a 9mm round that was for sure. Am not sure what it was. was a tad longer then a 9mm, the case was necked down a bit as well for the bullet. So any ways take it in to the store an show it to the guys. Turn out they had had a few diff calibers spill together an then had to sort them all out. Really nice guys an all but if I had not paid attention to loading because I was counting out 10 rounds I might have not caught it. :banghead: An if that had happened An I had fired it I am sure my gun would have gone boom in a bad way. So the question Have any of you ever had a simmilar instance. You are loading your clip mad or cylinder an caught at the last minute a round that was close to what you were shooting but not.
