Is 8.25" barrel too short for even the 300 BLK?

I've read that the 300 BLK was designed to burn all it's powder in 9-10". So is 8.25" pushing it a bit?

I went 12" for a nice balanced package with a Sig Brace.....it's plenty short with great performance numbers!

8.25" is perfect for 300 blk

Since there is more than one powder...barrel length, load and gas port size can be varied to get the balance you are after.

300blk is great in shorter barrels. 8-12 inches should be right in the sweet spot for this cartridge.

Nope 8 1/4 is good.
The only reason I went with a 10 1/2 for mine so later on I can go from a pistol to a suppressed rife.
