I’m going to guess a rifle able to take Lapua would be heavier than they wanted to take up and down the mountains.
I guess you may be right. Never fired that round so I don’t know if it fits a standard length (30.06) action.
I picked up an AR-10 in 338 fed last week. She weighs like 2 stags and I’m wondering if in the end, I’ll be using the 6.8 spc more than I want. AR-10 feels like M-14; just too heavy except on atv or snowmachine. Keep it a trk gun more than likely.
