Thread: Reducing charges for lead projectiles.

From the ADI website:

.303 British.

Bullet Powder Bullet Diam. C.O.L Starting Loads Maximum Loads
Grs Velocity (fps) Pressure Grs. Velocity (fps) Pressure

150 GR. HDY SP AR2208 .312" 3.008" 38.0 2410 35100 psi 43.4 2710 48800 psi


For the lead projectiles in both .303 and 30/30 I have some pretty old data for IMR4064 which is listed as an identical burning rate powder. Didn't worry with gas checks and kept velocity under 2,000 fps. In the Martini I used a full case of Pyrodex (didn't want to possibly ruin an old gun with smokeless loads).

Although I do confess I haven't fired the lead rounds in quite a while as I stopped CAS shooting several years ago. Just in the process of getting back into the sport now.
