    1-9" twist would be good. I shoot 55gr most of the time.

    300 blackout market needs a NR barrel. I would buy a light to medium weight for sure myself.

    Wonder how .300 blackout would function in an 18.5”? 10.5” barrels are kinda the sweet spot for that cartridge from what I’ve read
    It's not that I'm new to this....I'm just an idiot...

    300 blackout was designed to burn all of it's powder in a 9-10" barrel. I think at 18.5" you'd start to lose performance. Personally I think the 300 blackout really only makes sense in a short barrel, suppressed carbine shooting subsonic ammo. Highly effective for CQB/CQC applications.

    My nr - 30 carbine (18.6 barrel)runs on the same powder as my 300 blk which has 16 inch barrel. Both rifles run fine on the H110 or 296 as well as A-1680. I also have a 300 blk sbr which will run fine on D4198 and or the pistol powders. Can't see why the 300 wouldn't be ok in 18.6 inch. Use a flat base bullet for max loading
