I dont have the bottom in a stock yet. I have a ton of different projects going this summer that are pulling me in 20 different directions. Now that my bandsaw is fixed, I need to pick up a couple of long compression pattern routing bits so I can just pattern out the blank shape with less screwing around.
Here are a few pics of where Im at.
I spent a good deal of time figuring out what the height of the bottom needs to be in relation to the action so it will actually feed as Im building a stock 100% from scratch.
I worked it out so that when the mag is fully inserted and it pressed into its most upward position at can be, it wont jam, but when the mag is hanging in a normal position it still feeds without issue.
Bolt coming in over the top of the mag when fully inserted and Im holding it up.
Bolt face engagement on the round. It feeds 100% no issues.
LRI Pillars cut to height and ready for inlet. Dont mind the angle on the front one. Some idiot did that. Wont effect end result as they are buried in Devcon anyway. The rear pillar has to be cut like that so the bolt release works correctly. Its a Savage thing. I like the pillars, but I dont know if I would use them again on a Savage action.
Ive tested with ARC, Accurate and MDT mags. All work with no issues. I cant stress how important it is to get the mag to action height correct for consistent feeding that never fails. This little exercise took me a few hours to work out to get it where I wanted it.
As far fit with a standard Savage cut bottom end? I dont have a pic of it, but I did set the Atlas next to my old Boyds stock that was setup for Savage mags, and it is very close to fitting. You would have to go in with a file and maybe a Dremel (carefully) and open the hole up a bit to get it to slide in. You would also need to check your bottom to mag to action height to ensure that it will feed reliably. Its easier to sneak up on this, slowly removing material until its perfect, rather than just making a cut and having to fill/shim/fix when you find out the bottom metal is too deep in the stock.
