Default 300 blackout pistol barrel length

Anyone have an opinion? I'm looking at buying a 12". Is there enough difference in energy vs the 9" to go with the longer barrel. It will be used for hunting.

I forget all the info, but I settled on a 10.5 inch barrel when I built mine. I love it!

I forget all I read too but it seems that the general consensus is that it burns all its powder in a 10" barrel. I built my pistol with a 8.5" Ballistic Advantage barrel. One reason I went that short is so I could conceal it easier if I ever feel the need. 5.56/.223 is really neutered in a short barrel but .300 was designed for a short barrel.

I hunt with an Encore 44 mag with a 12" barrel. Is yours a single shot too?

12" is fine, but you will have to build it in pistol configuration unless you plan to form 1 it...

Thanks for the input after multiple articles and videos I'm going with a 10.5 inch in a pistol configuration. It's crazy that you can buy a complete ar for 400 but have trouble staying under 1000 building a pistol.

you need 10" for a full powder burn in the x39 so I am thinking the 300 is close to that 9-10.5". Now if you will be suppressing the longer the better as some manufacturers want 10" or better.

How bad is the recoil? My 44 is as bad as I would want.

8" is what you need for full powder burn... mine is 8.3"
