[QUOTE="Long Time Long Ranger, post: 528352, member: 505"] With the mk 5 action you can easily convert it to any magnum you want. If you never want to do this again open the bolt face, lengthen the slot on the bottom of the bolt for the 378 case, and get a 378 magazine follower from wby. Then put a 338-378 wby barrel on it. Then you have all you can get well beyond the lapua. I just got off the range and shot my 338-378 again this morning. It is pushing a 225 grain .65 bc bullet 3530 fps and shot a 1.35" group at 400 yards. This gun has been shooting great for many years. That is why I have seven 338-378 wby's. It has a 28" 1-10 Hart barrel on it. A big rifle like that is just way cool to shoot. It will average 200+ fps over the Lapua and RUM's. It will consistently hold 7-8 inch groups at 1000 yards which is exceptional for a 10 pound scoped out rifle. [/QUOTE]
