Since this thread has taken a turn away from the origional question about 310gr bullets, I have one about Sierra 225gr. I reload and shoot them thru a Rem 750 .35 Whelen. They shoot very well averaging about 1.5" at 100yds. I have not chonographed them yet but they should be at around 2400-2500fps. Is this bullet at this velocity going to give good performance on game from deer to elk? I don't get too caught up in the complete pass thru vs expending all energy in the animal debate. I just want a bullet that will hold together enough to get the job done.
