This might be true.I believe that for optimal performance you need ~9inch barrel.
your milage may vary depending on powder/projectile combo.
they sound like they hit harder on steel at 100 yrds too vs 45acp.This might be true.
In my head the 200+ grain 300 Black at around 800-1000fps is a glorified 45acp with better bullet coefficients. Get a fast enough twist, they should stabilize.
My son, who was a USMC armorer for a decade, tells me in his experience the sweet spot for 300BO is about 10". Which is why I bought a Ballistic Advantage 10.3" barrel for my upcoming build. Agree, YMMV and of course this is very load and application dependent. One opinion.....I believe that for optimal performance you need ~9inch barrel.

I heard the same so I went w/ 10.5 myself.My son, who was a USMC armorer for a decade, tells me in his experience the sweet spot for 300BO is about 10".

Ya, the Sig is definitely a very nice little rifle! Have you had any issues with subs tumbling?
I found two short barrels, a bit rich for my blood. But at least I know they exist!

Just need to find out if any one has run something this small on there AR and if they run well!
Ya, after you posted the twist rate I rechecked those two barrels. Darn.
