RL-15 and BL-C(2)
It’s what we had on hand. Been loading for a gas gun. The RL15 behind 168 Berger’s shot well.
The BL powder behind 168 ABLR’s started at 2700 FPS and went to 2826 but didn’t seem to have the accuracy I get from the ABLR’s in my 7 mag.

From what I saw in factory ammo and the Berger’s, and based on the responses here - I think 2600 will be the accuracy node I will play around the edges of.
I loaded some Berger 168 and 175 VLDs and playing with seating off the lands really helped with accuracy. But I mainly load to work in the magazine box so at 2.800" factory specs I was still able to get around 3/8 moa pretty easily in my PSS. Right around 2750 fps for both and flatter trajectories. I'm pretty sure that was with RL15. YMMV. I still have some IMR 4895 and H4895 left so that's probably what I'll load the last of my Berger 168 and 175 VLDs with.

125gr TNT over 52gr of WIN748 has been an exceptionally accurate load for me. 22" barrel on a ruger american does 3200fps. This has become my knock around deer and antelope rifle out to 500yds. Light weight and ugly as sin with a 12x SWFA but darn if it doesn't slap the **** out of them....

8208 xbr does well with lighter bullets. Not tried anything above 150 grain.
I have 6 lbs of 748 but never shot it in my 308.

I have a R700 varmint that I had cut down to 20". I use RL 15 in combination with 165gr Sierra SBT's. I get around 2550fps with an average .307" center to center at 100yds.
