I have some questions about stocks for the Savage Target Action.

Are there any good 'drop-in' non-Savage stocks that fit the 3.44 inch hole spacings? Similarly are there any good 'drop-in' non-Savage stocks that fit the 4 inch hole spacings? I am trying to get an idea of whether there is a big difference in the after-market support for these two different hole spacings.

With 'drop-in' I mean a stock that was created for the purpose of specifically supporting the Savage Target Action (all three action screws) without having to do a lot of work / reshaping.

The purpose of this build would be an F/TR rifle in 308 with a 30 inch bull barrel for shooting 600 - 1000 yards. I am looking to preferably stay in the $500 - $600 range for the stock.

Any input / recommendations would be appreciated.
