Ammo in a 1 to 10" twist .308

It's a 24" Douglas barrel on a Savage 12 F/TR. The gunsmith says this barrel is 1 to 10" twist. (He's re-bedding it)

I asked & he said I should be able to fire 155 gr bullets, but it may be over-stabilized at that twist rate. What do you think?

I have a 1:10 .308 that loves 150's...but I swear I think it shoots everything well

The answer is maybe....

Only way to know is work up a load...many hours of "work"

Find the heaviest bullet it likes and your set :-)
my 308 has a 20" 10 twist and it likes 175smk and 190smk. It shoots the 175 good subsonic and super sonic.
When you spin a bullet too fast it can start to 'wobble' too many rpms and it will show the imperfections of how well the bullet is balanced.
Let us know what you come up with.

Just try the 155's out. I used to use 168 Hornady and Sierra Match bullets in my NM M1 Garand, with great results.

Well, the brown truck just delivered 200 155 SMK's. I got this rifle to try my hand at long-range shooting - up to 600 yds. I confess I've had trouble sighting through the super sniper, so the gunsmith is going to move the scope forward a bit, hope that helps.

I've been working up loads for 175 SMK with Varget, IMR4598, IMR4064, with rather poor results. Mildot said he was running Lapua 170gr lockbase, but I was unable to get those & got the 175's instead. The 'smith (Doug Wasson) said re-bedding should help, oh and there was a trigger lockup due to the back of the Savage trigger assembly touching the stock, and he's fixing that too.

I've got a few different powders to try (W798, IMR3031, and IMR8208 XBR). I know it's not the powder, it's me, but I want to try them all.

I love the challenge, and I appreciate all the advice., so will give range report soon.

I'M a fan of the 168 bullets

I know, a lot of people swear by the 168 bullets. Guess that's next on my list of to-do's. Gonna try the 155's first - just as soon as Doug finishes re-bedding the action & fixing the trigger prob. - I'm loading up rounds today.

im gonna be in g ville getting junk out of storage.. i got a box of molyized 168's your welcome to try out
