I believe both of your trigger suggestions are possible... The jewel is my biggest ?... there is a Savage 2 trigger however. Axis still has the floating bolt head too. Best way to go would be the Axis 2 in my opinion.... As long as the stock you really want to put on it is compatible.

As far as accuracy, Yes, I think it can be as accurate as the 110. it's just a matter of how much tinkering and aftermarket parts you add to it.

My Axis (22-250) will now put 5 in a nickel @ 100 yards... (maybe a dime with a better shooter) I added a Criterion barrel, the Prairie hunter stock, and modified my stock trigger, but that's it.

I probably would have built my 260 rem off an Axis action, But I'm left handed and there aren't as many options out there for me when it comes to stocks, so the 11/111 action is what I built my 260 on.
