Yep, 1 thing about Shepherd is they do get bad publicity. Do a search over at 24hourcampfire, and longrangehunting.com and u will see more of both good and bad comments. Take a good look tho at the bad comments--most of them have to do with the reticle not zeroing precisely to the cartridge's trajectory. This is gonna be the same regardless of which generic ballistic reticle u get. Don't expect it to zero perfectly, especially when u get beyond 500-600 yds. when meteorologic changes begin to affect the bullet's trajectory significantly. And u can forget about the reticle-rangefinding qualities of any reticle beyond 400-500 yds. or so. It'll always be better than guessing, but not accurate enuf to get u withing 20-30 yds. of true distance all the time. The MOA. or inch per hundred yd. system that they have in some of their reticles will be more accurate once it's understood and applied properly, tho still lacking in accuracy at long-range on tgts. of varying dimension.
I've not seen any comments on the reticle not holding zero tho, that i remember. Probably so, i had that problem with an old Redfield i owned way back when, and other problems with a few other name-brand scopes. Had a buddy that had to send back a VariX-III awhile back because it wouldn't track correctly. It came back fixed. so...?? As in most purchases in this world--u pay money and take chances.
