Re: bsa sweet 17
i used to use BSAs before. 3 of them as a matter of fact. 2 of the supposed top of the line target platinums. after about 3 years they got all greyish and dark. then they wouldn't hold a zero. i sent 1 back, when i got back the replacement, the same thing happened within 2 years. when i got a replacement for that, i gave it away for free. i will never get one again, even if someone want to give me one. seems as soon as you tweek everything out, the scope goes bad and you start all over again. that was on a .22 lr, and a Ar-15.
you'ld probably be better served with a centerpoint, tasco, simmons, or even a barska (for something in the same price catagory). spend a couple of hours with some ammo and make up some scope dope on what is actually happening with your actual equipment.
different ammo shoots differently out of different rifles. if you don't happen to have the same set up that the turrets were based on, the turrets don't matter too much.
granted you'll still be in the neighborhood, by an inch or so depending on distance, but nothing beats real data from a real setup.
i was never a fan of the pre-determined reticles or turrets for that reason. just my 2 cents.
