Ok I was not going to respond to this but ,, let first note that i would not hunt with a ncstar becouse my t/c scopes are far better on eye relief.. but at the target range on a rest ncstar works fine and i was putting these scopes on a 17,22,22-250 well i wanted to see if they would hold up on a heavy hitter so i put it on a 454 encore and so far it held up 40+ rounds not saying it wont brake the next round i shoot but it held up so far what did not hold up was the rings that came with the scope i had to replace them with millet steel rings .... i say give them a try
