So my gun has not shown any preference for bullet or velocity. Everything I shoot factory and handloads groups in .4 to .6 moa range. No special magic nodes where it goes into one hole groups but also no special nodes where it will not shoot .5. Cool bore hits same hole as hot barrel. Being this gun is my hunter gun I'm VERY happy with how consistent it is and I have never had a gun like this. Usually they are bullet load sensitive. How many have a gun like this that just seems to shoot anything well? All I did was bed lug and tang area when I got it. Thus far I have shot factory winchester LR 142AB's, factory Fed 120gr, HL's using RL26 with 143ELDx, velocities have ranged from 2600 to 2900 all so far .6moa or better. With my HL's it shoots 47 gr RL26 at 70 degrees .4moa and same 47 gr at 100 degrees .4moa even tho the speed went from 2848 to 2878. I've never had a gun this consistent. I shot a 1.5" 500yd group last week although 2 other groups were 2.5".
