Bolt Action 7.62x25 SBR
Pros:
Many 7.62x25 rounds were manufactured to shoot out of Sub-guns, so a 8-10 in barrel on a Bolt gun could still take full advantage of the round itself.
OAL could be 26.5in (good gun to toss in your truck, or use as a varminter, could definitely walk through the bush with it).
Mag capacity could be quite high as they'd be designed for a bolt action (or could use existing Tok or P762 mags).
Very easily cleaned if you used Surplus through it (and thus ammo could be real cheap)
Not scary looking.
Cons:
Could make Bolt action precision rifle purists really mad???
I'd imagine it could be relatively simple to design (wood stock, maybe a modified short action similar to a CZ 527) though I couldn't imagine the production costs.
