Single shot to mag

I'm kicking around the idea of switching the action on my model 12 22-250 from single shot to detachable box mag. Thinking something like the CDI AICS mag style.
The details on my rifle: model 12 22-250, blued 2nd generation short action, flat top bolt handle, top bolt removal, Stainless Steel bull barrel.

I typed in my serial number to savage arms part finder and it came up with:REC RH S/NM RD SR 110 (NEW MAG) - P/N: 106091 $157.00

Which I believe is the blind magazine. From their picture it looks like a round top bolt though.
Would this be the right way to go and then convert to DBM or is there a different action to run?
Also what kind of clip would work with 22-250? Would that be .308?
I have read talk about center feed and stagger feed, is center feed the way to go with this?
I know I will be switching stocks, wanted to do that eventually anyways.

Any ideas are appreciated, thanks in advance!

So I think this the bottom metal I would need since my bolt spacing is 4.275 : http://www.cdiprecisiongunworksstore...eed-4-275-dbm/
Does their conversion keep it stagger fed or does it switch to center feed?
I'm having a hard time figuring out which action though. I have been looking at this in the FAQ:http://www.savageshooters.com/conten...Parts-Tutorial
to find the right action. Not sure if I need .308 or .223 for my 22-250 because I'm not seeing 22-250.
Any suggestions on a action? Am I heading in the right direction with the bottom metal?

When looking through the Choosing the right DBM bottom metal tutorial they list multiple "G" prefix serial numbers which I believe are the round top actions. I have a "F" prefix which is a flat top. I'm having a hard time finding a repeater, flat top, 4.275 bolt spacing, 2nd generation short action serial number to order parts. Anyone know or have something either DBM or blind box?

Or does it not matter if the parts are round or flat back, will they interchange?

They will not interchange. Look at ptg or accumag. I'm not sure if they have your spacing but I've had the accumag setup and it was great and my friend ha a ptg setup and I may go with that on my 7.62x39 build I'm starting this month

Atlasworx, CDI, PTG all show 4.275 bottom metals

Nice! Thank you for the options on bottom metals!
Any ideas for actions that would work?

For the 4.25 action any short action flat back 10,11,14,16

Thank you this helps out alot!
One more question I have, for the mags should I go with a .308 to fit my 22-250 rounds?

Yes

You're amazing futureider! Thank you for all the info it will help my build get off in the right direction!!

I know am but don't let the secret out.
Good luck post pictures
