There's powders that'll do it, but not at safe max pressures.i would like to find something where i could push the bullet around 2800 to 2900 fps with a 24" barrel if there is anything out there that can get me to that point.

The only barrel-length vs. muzzle-velocity I ever did was with a 22, 24 and 26 inch barrel all with virtually the same .308 Win. chamber and bore dimensions. Using the same lot of handloads giving a 25 fps velocity spread about a 2680 fps average in the 26 inch barrel, the 24 and 22 inch ones shot 168's out 48 and 42 fps respectively slower. That's about a 23 fps per inch difference. SAAMI's own tests show about the same numbers. Check out page 22 in the following link:You will lose about 55fps per inch shorter than a 26"barrel.
Cloverleaf groups have all shot holes touching. That's 3/10ths of an inch center-to-center for the largest one. "groups" implies more than one group. All were 3/10ths of an inch or less at 200 yards? That's .015 MOA. Wow!!!!!I just worked up a load for my Sako .300wsm with a 190 grVLD. 200 yard clover leaf groups.
Just one group? Fine.Typo...I meant group. I wish I could do it over and over.
