If you want a shorter action, the .300 WSM
is also a good choice.
***as is the 270WSM***
If you were to remove the limits on caliber of choice I would have included the .264 Win mag. **(.264) That is a 6.5** American vs Canadian math. Kinda like 7mm/.284 or 7.62/.308 or 6.8/.277 or 5.56/.223 etc.
The two I use most frequent for that exact purpose are the 270WSM shoving 140Accubonds at 3100(factory Win-70 fwt) & my custom Win-70, 300WSM shoving 180Accubonds at 3100+
I've had outstanding performance with both.
Yes, I realized after I posted that part of my post made no sense. I wasn't thinking. I apologize and definitely know the .264 Win mag is a 6.5 MM, in fact it was the first 6.5 to be popular in the US.
