Bolt face sizes and blind magazines

I am looking for a savage bolt action rifle that will accept a .392 bolt face short action and a blind magazine. does savage make such a combo? the .223 rem is .378,,,,, inquiring minds need to know as I want to build a custom rifle for the 7.63 Mini Whisper of SSK fame..which it is the 30 Mauser case with rifle bullets ,,,, according to JD Jones the 7.63 mini whisper is a little to short to feed from the magazine... but I am a dental tech and I dabble with small metal parts all the time so I think I can massage the magazine to accommodate this small round.... or at least give it a try ,,,and at the very least come away with a single shot rifle..

Because the blackout is easy to do but this one is tough to do?

yeah the blackout is easy to do in a AR platform but what I want to do is put it into a bolt gun that will be a repeater....not a single shot
