I understand that 2207 can be used for lead projectile rifle loads, does anyone have a link or an idea of what to put behind .303 gas checked 200 grainers please. I will be doing research other than this but its a starting point.

Greetings @johnd,
My old Lyman Manual lists 21 grains start to 24 grain max of IMR4198 for the 213 grain in the .30-40 Krag. AR2207 is very close to IMR4198 and the .30-40 Krag is very close to the .303. The velocities were 1,554 and 1,769 fps respectively. These loads were not pressure tested so work up slowly.
Regards Grandpamac.

Lyman lists 20.0 t0 26.5 grains of 4198 with a 200 grain cast bullet the 311299, 2207 is slightly slower burning in my experience in my .222 RemQuote:
