thanks for the advise, I use 170gr core lokt bullets, and I have a Nikon scope on it to. Usually my shots are well under 100 yards and i sight it for 50, but last season I missed a deer at 200 cuz it went low. So im thinkin i might as well sight it in at 100 if there isnt much rise in the bullet that way i know where to aim if that long shot happens again. It probably will because its a slope that gets all the sun in the afternoon and the deer usually go there to hangout and rest and there isnt much cover to get alot closer. Well thanks for the advise, hopefully the 170gr sighted at 100 yards will do the trick
