chambered, if you have access to Barnes bullet lengths, you could help jbm fill out more of their bullet length data base. Or if you have a digital file of Barnes bullet lengths, send the file to me. I'll be interested in the lenghts and updating jbm.

The most common bullet weight for the 308 is 150grains (shorter bullet) and their twist rates reflect that

many manufactures are now producing .30-cal barrels with the same twist for cost savings. Looks like Savage and Ruger use 1:10 twist which for me is an improvement for the .308. Sako and Tikka seemed to have compromised at 1:11 which spoils the .30-06 for me. Remington still makes separate twist rates for the .308 and .30-06.

As does Weatherby and Browning !!! Savage offers the 1-12 and a 1-13 in their target models !!!

I've been using the Quick Loads bullet database !!! Here

Thanks, great site for hard to find information. A lot of work goes into a database like this.
