If it was me---- I would look to go 6.5x57AI that is if I wanted to increase velocity. I would need to check to see if the 57 case will function in the short model 70. And I would go 24". That is what I would look at. But the 260 case will not be useless by any stretch of the imagination.
Bullets ---95 gr. Vmax for all things varmint and any of the 120 gr. to the 130 gr. hunting bullets for all things eatable. It should do everything my 6.5-06 does out of a short action. You might need a larger freezer.
