The 1/2 MOA clicks wont be a problem. Simply means the point of impact wil move 5mm at 45yd instead of 2.5mm with 1/4MOA for each click. Once its zeroed its zeroed for HFT whatever the clicks.
Forget the adjustable mounts, wont make a scrap of diference to the scop clicks. For HFT you should get the scope as low as possible and shouldnt need elevation adjustment. These are for FT boys who use them instead of scope packing. If you need them use Sportsmatch, B-square are a PITA and loose zero.
Make every shot count
