That Leup is a good choice. I prefer lower power ranges, but a good rule of thumb is 1X for every 100 yards.
So, a 14x is sufficient to 1400 yards.
Plenty of great scopes avail with those power ranges. Check out a few before buying one.
USO will make one with every option that you choose, and they are made in USA.
I like the IOR 3-18 FFP for a good all around long range scope, and it is hard to beat for anywhere near it's cost.
