VA- the 9.3 would be potent no doubt, and a handy hammer
O45- the Max would be neat, having shot the little brother in a rifle, the Max would really be something - very efficient! Could sling 180s well - even spire points. Heavy LBT? Interesting!
Obear- are your 6.5s in M-S rifles?
If Ruger were so inclined they could do a ltd. run in various calibers/configs, a few a year. How hard is it to just change a reamer and then stamp the bbl?
Bet they could sell runs of 100 pretty quickly.
