Guys,
I know a wee bit about optics here..... in addition to buying rifle scopes for the last 30 years, I've been a semi-pro photographer for the same length of time, & I've also built from scratch, right down to grinding & polishing the main mirror, an astronomical telescope. You do learn a thing or two with that bit of exposure.
DON'T get caught up in the "power" numbers of the magnification. Magnification is secondary to having large diameter objective lens, which is the primary factor in the sharpness & resolution of what you see when looking through a scope. The quality of the lenses is also a determining factor. It does you no good whatever to get a cheap scope with a small dia. objective and high power magnification. You will most likely be looking at a target which appears to be large & close up, but which is so fuzzy that you can't see .50 caliber holes at 100 yds.
20 power is plenty enough magnification to see even .22 cal. holes at 100 yds, & even sometimes you can see them at 200 IF, & i repeat, IF the scope in question has good quality lenses and an objective lens of at least 60 mm.
I have seen cheap scopes of 30 to 45 power that would not plainly let me see .30 holes at 100 yds. in bright sunlight. Just a blurry mess.
In optics, more so than in most other things, it is definitely true that, "you get what you pay for". Don't scrimp on cost, buy the absolute best you can afford to splurge on and you won't regret it in the long run.
Another thing.... If you plan to shoot Highpower Rifle, or just do a lot of position shooting with a sling, or offhand standing, DEFINITELY make your choice of scope one with a 45 degree angled eyepiece. Trying to look through a straight eyepiece scope while "slung up" without disturbing your position is an exercise in frustration.
If all you are doing is bench shooting at no more than 100 yds., any of the Bushnell scopes should be fine. Decent optics, not expensive. Even at 100 though, I've seen Simmons & BSA that were little better than 5 & Dime store plastic toys. Don't waste your money.
If you do ANY shooting past 100 & need to actually see bullet holes in paper, there is no substitute for quality, & that ain't cheap.
Just my opine.....
