I've got an opportunity to trade a Sako 75 6mm ppc usa for a Rem. APR .300 RUM. I don't know much about these Custom Shop rifles, I hear they are supposed to be more accurate than most off the shelf guns. Can anyone tell me more about the APR, and if I should follow up on it? There is also a NIB .300 RUM sendero II to be had. I can't decide if I should keep my Sako and just buy the sendero, or swap for the Plains rifle. I feel that I could get more use out of an accurate .300RUM than my PPC, the only varmints I spend/waste much time and energy on are deer.
