You can find the Leupold easily in Cabelas, but you might consider the Tasco first as it is about half the price and works quite well. Try Natchez shooters supply as a source for the scope. Of the available non-custom mounts, I would take the Scopemate2, it range adjustable and very well made. Not as easy to find, but way superior to the HHA IMO.

If you can't find one e-mail me, my local dealer can special order one for you. Only downside on special orders is no return, but it's a great mount. You'll like it very well I am sure though. The Scopemate 2 adjusts easily for yardage, but more often than not I leave mine set at 30 yards. Anything fro 0 to 35 yards will be within 4 inches higher to 4 inches lower than the point of aim with my setup. Makes it easy as pie. Do do have other marks and hold over spots, but unless you are out west, I doubt the would come into play. You will love the red dot setup. Have fun.
