    Thoughts?

    They both are short actions, both use the same barrel size (.300AAC has 5R and a different twist).

    I have a Rem 700 SPS Tac in .308 Win in 20" and a .300AAC-SD (threaded) 16.5" and I have rolled the idea around to convert the Blackout to .308 Win to have a shorter barrel rifle that's threaded.


    To me... It appears that it would need the obvious rechambering AND a new bolt to handle the .308 face and a different internal magazine box for the longer round.

    Besides the three things listed above; what else is stopping this from being done?

    Yes I like compact rifles.

    Google turns up NOTHING on this. I mean one could just get a different barrel but I'm thinking rechambering is cheaper than having a new barrel put on it.

    Any idea what the current twist rate is?

    new bolt is not needed!

    @Velzey
    Don't forget the parent case of most .300AAC rounds is a .223 case:

    Either needs bolt machined or a new bolt.

    small bolt face has plenty of material to be opened up to the .308 not an issue

    But then you would lose your rifle your going to use for your suppressor !! And that barrel is a 1:7 twist...hmmm

    Know if we just knew of a gunsmith around here...o_O

    I misunderstood. I was thinking you meant use it without modification. Of course that's silly beans!

    It's nothing I plan to jump on quickly or maybe even at all.

    Gunsmith.... Hmmmm.

    @Velzey , what's your thoughts on that 1:7 twist for bullet weights and being in a 16.5" barrel? Would have a loud bark with medium loads in .308 unless using a fast powder to ensure burn in that time (doubtful). If this were taken as a project how far away is the Salmonberry wilderness and what kind of wompum would be needed to accommodate this?
