well to be quite honest with you, I've never benched it at 100 yards. I sight it in a half inch to an inch high at 50 yards. And it's open sights so it's hard to get groups like you would with a scope but I would say at 50 yards, benched on sand bags, I can safely put 3 shots in ohh a bit less than 1 to 1.5 inches?
I've never calculated it and to be honest I think it's much better than that but like I said, open sights, on sandbags as a bench...
But where I hunt, I will never or very very very rarely get a 100 yard shot, so I havent spent the time trying it out at a 100 yards.
It does group well tho, dont worry, it's not all over the place, and it's easy to sight in.
For 200$ you will get a nice black powder rifle, it wont turn into a paddle. :mrgreen:
Oh and I'm not sure but I think you can only put 100 grain (2 pellets) of powder in it (short barrel). Not sure on that, you'd have to ask the dealer, but if you ask me, 3 pellets of 777 is really not needed unless you're shooting at more than 100 yards consistently...
