Hello all, first time posting here. I have a few questions about building on the Savage action. I'm looking to buy a Savage 10 .243 with accutrigger to build on. Guy wants $325 for it, and that seems pretty decent. I want to build a .223 AI on it though. Now, the only thing I should have to switch out is the bolt head for this action to work with the .223 AI correct? Obviously I'd need a new barrel, but McGowen offers a .223 AI prefit for the Savage...which is the road I'm looking at going down.

I'm just not sure about compatibility issues with this action and the cartridge I want to build on. What is the mag box length on the Model 10? Is this a small or large shank action?

Thanks!
