Twist

The 1:10 twist was originially determined to be correct for the 220 gr bullet that was loaded in the .30/03 prior to the adoption of the 30/06 with it's 150 gr bullet. Guess what, the 1:10 was kept as standard for that cartridge and works well with a broad range of bullet lengths and weights from 110-240 grs hunting bullets, although a 240 gr match bullet is long enough to require 1:8. That 1:10 twist will give you plenty of latitude in your .308, and 210gr match or VLDs probably fall within the ideal range.

One in 10" twist barrel will stabilize all 308 bullets except the Sierra 240 gr.
One in 14" twist will be good for VLD/ULD bullets up to 210 gr.

I've only seen bullets sold by weight never length.
 
The rule of thumb I've heard is that 1:12 is good for 168's and if looking to go much past 175's then consider a 1:11 or 1:10. Having said that though I have shot 1:12 ROT that loved 175's and were seeimgly unaware that they 'didn't have enough twist' ti handle the projectiles they shot so well :)

So? The physics of the situation and the economics are seperate matters entirely.

I have some 0.308" 260 grain bullets that are well stabilized by a 1:10 twist, yet you say that the Sierra 240 grain bullet won't be. The difference is the length.
 
"...what bullet weights would be best?..." For what purpose?
"...difference is the length..." Yep. Making a bullet longer is the only way to keep it a .30 cal.
"...1:12 is good..." Too slow. 1 in 10 is the standard for .30-6 and .308.

Original question was what bullet "weight" is stabilized. Do you think the OP is interested in shooting cast or powdered tungsten. Of course it's all about projectile length. So that would be a great answer for a different question

The original question was as nonsensical as "How long is a piece of string?"
He needed to re-frame the question so he was asking a question that could be answered.
The Berger 175 grain Match Target BT Long Range bullet is longer than the Hornady 220 grain RN. (note that both are factory-made jacketed bullets of conventional construction)
So if a rifle will stabilize the 220 grain Hornady, does that mean that it'll also stabilize the Berger 175 (or the 185 or 210)?

You and I both know the answer is "Maybe". So to get a better answer, a better question needs to be asked.
