Re: long range shooting optics
Well, here's an option at the far end of the scale from the U.S. Optics glass...
the infamous SS series of scopes, as sold by SWFA.com. Formerly made by Tasco, hoping for a military contract (there had been some buzz at one point about Leupold discontinuing the Mk IV lineup back then), they come in fixed powers of 10x, 16x, and 20x. Heavy, 30mm tubes, 42mm objectives, large tactical/target turrets, mil-dot reticle, 110 MOA windage and elevation adjustment (10x model).
I've had one of the 'early' SS10x42 models (circa 1998 or so) that I've abused a fair amount on coyote and prairie dog rifles, target rifles, etc. Had a variety of Leupold LR/T scopes, always ended up back w/ this one as a 'control'. Ended up getting another one (SS16x42) earlier this year. Most people I've talked to that that have these and have used them a lot like them. These scopes (16 & 20x models) have been used to win the Canadian Long Range championships several times, so they ain't shy on capability, as long as you can get over have a 'cheap' scope on your gun.
Not a U.S.O. scope, but they work well enough for me. Someday I hope to save up $$$ and maybe get a NightForce NXS for the variable power, but for now... the SS16x42 seems to work pretty well.
