Just booked an Idaho elk hunt for this fall, and was looking for some input on the 280 Ackley loads for the hunt. I will be taking the 338 planning to do a lot of glassing and hope for the opportunity at a 700+ yard shot, but want to take the 280 as a back up rifle. This will be my first elk hunt and I know there is a wealth of knowledge on here. any tips on bullets, powder etc. for elk with the 280 would be greatly appreciated.
