Perfect 300 BO barrel length?

[lftd&pwrstrok'n]

I am in the process of getting the parts together to build a 300BO pistol. Been doing some reading and see that a 8"-9" barrel is needed to burn all the powder and the velocity gain by going longer is very little. But, my question is, does a linear comp (ie. Flaming Pig) actually help w/ burning any powder? Let's say I do a 7-7.5" barrel, would the 3" comp make it essentially a 10" barrel?

I want to go as short as possible, and only building it, well because... I don't have one

Also, who make a good barrel that won't break my bank?

No a linear comp will not give you the full effect of a longer barrel.

I didn't really think so, but was hoping to be wrong.

I built my 300blk pistol with a Ballistic Advantage 8" barrel, 1/7 twist 5R rifling, from Lanbo's Armory for $88. It's nice!

I’ve been looking for 8-9” in a lightweight barrel for hunting. Most likely will get the Faxon 9” gunner profile. Lighter than any of the other 8.5” barrels I’ve found and it gets good reviews.

8" to 10" is all you need. You will likely bottom out with anything longer unless you are hunting some serious hawgs.

I LOVE my 300 black pistols, full length, and SBR. Flaming pig question has been answered. I have one with just a thread protector that is 8" It is so stinking cool.

I have a 16" rifle already, pretty much bored and wanting a pistol. One of these days I am going to suck up the whole tax stamp thing and join the NFA game. Thought a short pistol in 300 would be good suppressed for shooting predators snacking on our chickens in the middle of the night.

The perfect length depends on your use case. What are you planning on doing with it?

For a full burn, it would depend on if you’re running subs or supers.
