I have the regular version. My stock touched up dront so before I even loaded for it I bought the hs stock. I did shoot some factory loads (fed match168 smk's)with the factory stock and it shot well. (if I recall correctly) it was around 1/2 to 3/4 moa. With the hs stock and hanloads it shoots 43.5 fr varget 168smk into a tiny little hole. I have shot several .25 groups and a couple under 100 tho. I have a defensive edge brake on it and it us unreal how little it recoils. I wish I would have shot these loads with the hogue before I sold the hogue, who knows, maybe it wld have shot just as well
