I was watching Tac TV last night and Larry Vickers was testing out the 10mm Glock 20 to illustrate the range that this gun has. He was shooting at a man sized target. He allowed himself 3 tries (I think he started at 50 yds.) and if he hit the target within those 3 tries, he would move back and make another attempt. He got all the way back to the 250 yrd mark, hitting it on his second try. He made 3 attempts at 300 yrds. but did not hit it. 10MM ROCKS Wanna kill these ads? We can help!
