Not that I'm going to shoot any competitions with them I always want to see how accurate my guns are, but I have a Marline 60, Umarex MP-5 SD 22lr and wife has a 10/22 I would love to see how accurate each one is with some good ammo. Problem is each gun may like a different ammo and I don't really want to buy a particular ammo for each gun. I would like to buy in bulk an ammo that works good thru them all. This is wide variety of rifles, but they all seem decently accurate @ 50 yards.
