I've not had my fac long , and have got 455 in both cal , 17 and 22lr , I can't compare them with any thing else , but I'm well pleased with mine
And I've found both rifles to be dead accurate
And same as walshie has said , don't think I could be done with changing barrells over and a re zero
I do,know one thing tho , your going to enjoy your self no matter what you choose
Atb and Good luck
