I just got back from Bass Pro where I picked up two boxes of Remington UMC 9mm Luger Mega Pack for the next few times I go to the range. I have read a few bad reviews and seen some youtube videos. The bad reviews said that a few rounds were pushed too far into the casing and others said they had a lot of no fires. Both however gave a decent star rating of 3 of 5. Overall the Ammo has close to a five star rating. Some say the rounds where it is pushed too far into the casing will fire fine, other people say it could make your gun explode. What do you think?
