I've got about 1000± of the 215s left over from playing with them in my F-TR rifles and I thought I'd give them a whirl in my 300WM (M70), so for those who load the 215 in a 300WM: Are you single loading? or are you loading to mag length? Looking at it here it looks like the ideal seating depth (putting the bearing surface back about 2/3 into the short WM neck is probably about ½ an inch longer than mag length in my M70. That's me thinking like a long range (1000 yd) target shooter. So for those that are running them, are the loads with 75-77gr of H1000 that are noted here single loaded or are you loading to mag length? At mag length there is a silly amount of bullet in the case. I've read a lot of posts here that talk about loads but I haven't found one that detailed the OAL or BTO for this setup.
