One thing I've noticed about my R93 is that no matter what ammo I put into it I get 1 inch groups at 100 yards. Now, the reticule of my scope covers 1 inch at 100 yards so I doubt I'm going to do any better than that but it is well possible that the rifle could do better.
Often you hear people saying that only one type of ammo will shoot in their rifle, or one weight of bullet, or one powder. I've shot everything from 110 grain V-MAX to 165 grain BT. I'm just starting reloading and the reloads, so far, go just as well as the factory stuff.
I have also found that if I buy 150 grain ammo it will shot to the same point of impact as the 150 grain ammo the rifle was zeroed with, at least to within less than the resolution of the clicks on the scope and with the 3 types I've tried so far.
Like many I was a bit wary of that bolt and the "over engineering" but now that I've been using one for a while I'm glad I went with the R93. I don't like the looks of it at all as I wanted a blued rifle with wood and ended up with a black plastic thing but after 5 hours in the rain last Wednesday I was glad not to have a wooden rifle.
