I was thinking of building either a 338 Lapua or a 408 Cheyenne in my next tactial rifle but my problem is actions for both of these cartridges. Also which would yall think is better out of the 2. I a looking for a repeating bolt action not a single shot. The 50 is way to much in my opinion for what i would ever use it for. But they are about to open a 1200 yard range down the road from my house so u never know. Lata
