76.5 gns of IMR 7828 with 180 gn Hornady BTSP and Winchester large rifle Magnum primers. 2950 fps from my Remington 700 with 3470 ft-lbs energy. Very accurate too.

7828SSC 68.5 gr under a 180 gr Speer Spitzer was the most accurate load I got out of my 300.

Reloader 25 at 75.3 gr using 185 gr berger bullet .020 of the lands and CCI mag primers are giving me .5 inch groups at 100 yards going to play with coal a bit to see if I can get .25 inch groups load is about 3000 fps coming out of my 29" barrel.

I used IMR4831 in the old days before I rebarrelled my 300. 180 NPT (protected Point) and 72 gr of IMR 4831 worked nicely.

Now that the 300 wears a 29" heavy barrel and is shooting 208 AMaxs I use RL22 and it looks like it's going to work really nicely. Running about 2950 FPS (not sure of the charge off the top of my head) and showing the potential to be extremely accurate.
