I just use Winchester 55gr Ballistic Silvertips...
sight it in so I'm an inch high at 100 yds and am pretty much a dead on hold from 10-275 yds... the trajectory is that flat..anywhere within that range, I'm touchin' the heart/lungs .. it is wicked on those critters and woodchucks .. crow's are fun also, they explode in a ball of feathers ...
