I have a rifle with a mag boltface that I'm going to rebarrel. I was thinking of 7mmRemMag, but anyone have any other suggestions? Remember it has to use the mag boltface. Its currently a 270wby sporter on a Mark V action. I'm going to use a varmint countour so I can shoot more than 3 shot strings. The use will be practicing out to 1100 yards and occasional hunting if I won't be hiking it up hills.
264 mag? 7 Dakota
? 7 Practical? 7wby? Accuracy would trump velocity gains in this decision.
What rounds have the best barrel life (mag boltface)?
Are any of these rounds reputed to be more accurate than others?
I don't have any real gaps in my arsenal.
What would you guys do?
