Yes, it's an alley:
The ammo I am going to start with is South African, mostly because the rest of my rifles like it and I have a gob of it. If it shoots ok, I'm good, but if it does not, I have several other options in the 150-155 range as well as FGMM 168's. Most of my local hipower guys shoot 155's out to 200, so I know the round is accurate, and finding a load that works is part of the fun of buying a new rifle.
I really like this set up, you can use the sight housing for up close, and the insert for longer ranges (get the Shaver inserts). The problem is that the first match I shot with it, when I pulled the rifle out of the cart for the third stage the tube portion was broken off, it is soldered together. Since the manufacturer wasn't interested in replacing it, I welded it with .023 wire. I wouldn't wait for one to break, clamp it up and weld it from the start.
