I put a SharpShooter trigger on my model 12 in 22-250. Installation was pretty easy when following directions, adjustment was straightforward and it shoots pretty well now. There is a little side play that I would like to get out but overall I would highly recommend the SharpShooter for a Savage.
If you are not comfortable doing the work yourself a gunsmith should be able to install and adjust for you pretty quickly and inexpensive, should take way less than an hour.
