Yes a lot of fun. Just got to be careful when shooting with groups especially if there are inexperienced shooters or kids around. I remember when my uncle took me shooting when I was a little kid and I started to load the clip and I accidently pointed the rifle in his direction while he was bending over to get ammo and he turns around and realizes I have the gun pointing his way while I'm loading it and he ran over and whacked me over the head and said never ever point guns towards anyone even if its unloaded.
Try an AR15 (M16) and a 44 Magnum. Those are nasty fuckers. You wouldn't want to be on the receiving end of either.
