Re: savage 110 build?
No. The Savage action is not generally considered stout enough for the big Weatherby and Lapua sized cases.
Some have done it sucessfully, but I wouldn't recommend it.
If I had to, it could be done on your action with the Lapua bolt head available from Midway and with the barrel conventionally shouldered. No barrel nut.
I don't think you could make it a repeater, it's hard enough to do with the RUM's.
