308 Twist? 1:12 or 1:10

I may be wrong in this but how I was told the 1:10 twist will stabilize heavier bullets, Also I'm 60 yrs old Ive been A Remington fan for 55 yrs I received my first single shot at 5 it was a Rem, Since their quality went to heck I stopped buying them I just purchased the Savage 10FCP-SR n a 20" fluted med hvy barrel its accu stock and trigger, I did switch bottom metal to accept ACI and accurate mags, This rifle shoots a 5 shot group at .345 @ 100yds
I love this rifle, I paid 585.00 for it my Rem Sendero cost 650.00 in 1997 but it was a true 700 and a beautiful rifle, No comparison to what Rem is putting out today. My LGS wont even sell a Remington today.

Both factors are at play -- compare a simple cup-and-core bullet, with a Barnes Tipped Triple Shock, for example.

Barnes solid copper bullets are not appriably longer than lead/copper bullets. The 55 gr solid copper TAC-X is almost the same length as an M193.

The TSX line are plastic tipped, so are slightly longer, but do not require extremely higher twists to stabilize.

I can only speak for my Remington SPS tactical in .308 with a heavy 20" barrel, which shoots .5 MOA groups with almost alarming frequency. These are handloaded 150 grain Hornady Interlock Soft Points sitting on top of 47 grains of CFE 223....nothing super fancy.

It's a 1:10" twist and other than an upgraded Bell and Carlson stock and detachable mag, it's a stock gun, complete with pre-recall X mark trigger. my Winchester Model 70 in 30-06 is also a 1:10" and I have no regrets.

I don't think you can go wrong with either twist unless you go above 180 gr bullets. My opinion is the .308 should not shoot anything heavier then 180 gr.

My Winchester Stealth has 1:12 twist and 26" barrel. It shoots 185 gr Bergers with uncanny accuracy. Never had a keyhole yet.
