Ok. I've taken a couple of screenies to show the accuracy of both the mauser and the garand from a distance.
First, here's where I shot the guns from, and I'm hitting the wall right behind the reticle
Here's the first grouping, with the garand being fired at the same rate as the mauser, which is pretty slow(note-I'm standing about 2 feet from the wall in this pic)
Here's the final grouping, this one with the garand being fired pretty fast(5 rounds in about 2 secs-the pic is also taken about 2 feet from the wall)
Each gun was fired 5 times in each test. I think it's safe to say the garand is pretty accurate.
