I'm in the process of building my AR 10mm w-16" barrel for hunting in western north carolina, i doubt i'll ever have a shot over 150yards but i don't know what range i should be limiting myself with it. I'll be loading my own so i will keep the velocity as high as i can with out lossing accuracy, so i am between 155 & 180gr. I am going to use hornadys XTP's as people seem to like their performance on game. So say i'll have the 180grs shooting around 1500fps and the 155's alittle faster, so what distance would you use them at. Most of my hunting would be in deep woods but it may open up sometimes.
Last thing i want is to wound a deer and have it die slowly if i try to out shoot the gun.
