20 inch 3006 barrels 1:9 or 1:10 twist

[TurdFerguson]

Looking at getting a short 20 inch 3006 barrel spun up. I usually shoot 175 smks, but will shoot heavier as well. I'm a fan of 150 grain hornady SSTs for hunting. When I use the JBM calculator, I get better stability with the 1:9 in an estimated velocity (3.09 vs 2.05). Would a 1:9 twist barrel be worth it? or is a 1:10 good enough? Am I overthinking?

Is this a trick question? Is the 1:9 more money or something?

Over thinkng. Same price

10 twist has been good up to 220gr for a 100 years now. 150s should be stable with much slower twist. 9 is not going to do you any favors over a 10 for what you’re talking about.

Don't over-spin if you don't have to.
Your 1-10" will be more than fine for any bullet you will reasonably ever shoot.

Too many people go running toward faster twist rates when discussing shorter barrels. The vast majority of the time, that is not an issue in the first place.

Fast Fact: If you are not going to run suppressed, you may want to budget a motorcycle helmet with full face shield to wear in addition to your ear pro because that 20 inch 30-06 is going to be like dropping a Flash Bang every time you pull the trigger!

Excellent, thank you guys, I think I will go with a 1:10 no reason to re-invent the wheel. True on the noise, I may go with a 24 inch again, or cut back to a 22 inch to make it is a smidge bit more maneuverable. Not planning to supress....
