What is the maximum charge in 303 Brit with a2400?

I'm wanting to push the 314299 as fast as I can with 2400 to check accuracy. Does anyone know the maximum load range ?:Fire:

My old Lyman 44th edition shows the following:
19.0 gr 2400 1628 fps suggested starting load and 24.0 gr 2400 1893 fps as max.

22 gns is the maximum I've gone to in my rifles, I think 24 is a bit OTT.

Pressure rises sharply with this relatively fast powder so safe handloading practices are a must.

Work up in small increments and be alert to any pressure sign

My velocity was hovering around 1900 fps with 22gns BTW.

If you want more speed and safer pressure margins then go for a slower powder.

Ok ! Thanks, guys!

I've gone up to 24. Accuracy fell off. I got best accuracy around 18 in one gun, 21 in another using that bullet.

I usually start around 16 gr of 2400 and work up for whatever .30 caliber-ish gun
