Twist Rate For .308 150gr Projectiles ?

[BeeKay]

I have a few barrels, and they were inexpensive , so I may invest in a good quality barrel sometime .

I also have a stash of 150 gr bullets that  I bought because they seemed like they'd probably meet my needs, since I'm not expecting to take shots of longer than 400yd, because that's the max distance at our range.                                                                                                                                                                                                                         

The bullets I have are assorted tipped HP hunting bullets and FMJs .                                                                                                                                                                                     

All the barrels I have are 1:10 twist.                                                                                                                                                                                                                                             

I'm curious whether there's a typical twist rate that's specifically preferred for 150 gr bullets.                                                                                                                                             

I've seen some tests in videos that seem to indicate that a shower twist rate is better for accuracy using 150 gr bullets, but other factors could have been the reason for the improvement.           

I'm thinking about a 20" barrel, but I haven't ruled out a 16" 

Thanks in advance for help

I have a savage 99e in 308, I believe the twist rate in it is 1/12. shot a lot of deer and elk, always used 150's

Thanks - I'm seeing some WC barrels that are on sale with a 1 : 11-1/2  twist 

One of those might be good

BTW - I meant slower twist rate not shower

1/10 has worked great with 150 gn flat based bullets in my AR. Will be adding a 1/17 26 in bull barrel to one of my bolt precision rifles for 110 gn Sierra Varminters. Had Shilen chamber the barrel for this specific cartridge. Whatta Hobby!
