I have some funny experiences to share when it comes to choosing guns and calibers for long range shooting.  I use to be a member of a gun club that went out to 600yds, but it has long been closed down.   When I was working on zeroing a DSA STG58 rifle at a 500yd target, I wasn’t getting any better than 10 inch groups at 500yds, but that wasn’t too bad considering I was shooting military ammo.   That is just roughly 2 MOA at that range and for a gun that was a standar barrel and not match grade, I was pretty happy with it.   I have had some issues with the DSA FAL mount I have, but since I have loctited the mount, it hasn’t come loose on me.

While I was shooting there,  an old guy showed up with a 45/70 and a 12 inch box that he was going to shoot.   He fired at 200yds to check his iron sight zero and it was dead on, he moved the box out to 500yds and asked me to spot his bullets for him.   He took one shot and hit just in front of the box and then made an adjustment.  I had one of several Leupold 3-9×40 tactical rifle scopes A few seconds later he fired a second round and nailed the box.   He said I could shot at the box if I wanted to so I did.   My gun could hit it, but I had about a 50% hit rate when shooting off of the bench while this 70yr old guy hit the box every time with iron sights.   I’d like to know where that guy is these days because it made me realize that just because you have a modern firearm, doesn’t mean you are going to be a better shot them some old guy with his 45/70.
