Re: Savage blind mag mod
You might want to go with the new removable mag model from Savage. They don't make one in 223 yet, but you can tweak the 308 mag to feed at least two rounds. If you are going with a 22-250 or larger case, then you are good to go with the 308 or the WSM removable mags.
Kevin Rayhill at Stockade Stocks is supposedly going to be making stocks for this action. His varmint stock with an adjustable cheek piece is a great stock and will cost you quite a bit less than the Mac.
