A couple of years ago, I put an SWFA SS 10x on my re-stocked and bedded Browning X-Bolt 300 wm. It is one of the few hunting rifles I have that I was happy to install a heavier scope. The SS 10x has good glass, and tracks really well. I have dialed it out to 300 yards and I'm sure with a little practice it would work well past this distance. I 'm not a big fan of dialing for hunting and I have figured out how to use the subtensions on the SS for shooting out to 300 yards as well. My only gripe is that it doesn't have a zero stop unless you're willing to do a modification. If you like dialing, it is a great scope for the money.
