in some of the older reloading books, elmer keiths load of 22grains of 2400 is mentioned with the 429421 bullet.
current reloading books use about 20.5 grains plus or minus a little.
i realize the composition of 2400 has changed, but has anybody loaded that 22 grains of 2400 behind that bullet?
and if so, what happened?
I have before I switched to H-110/W-296. Infact I’ve gone as high as 23 grains. Factories in 60’s and early 70 loaded 240 44 mag loads to 1400 plus FPS. in fact Brain Pierce wrote that Winchester loaded a 240 grain jacketed to an advertised 1650 FPS thar got closer to 1t50 in actual revolvers.
I don’t know how much if any 2400 has changed but I do know that the old standard pressure fir 44 mag and 357 mag was 40,000 CUP but was changed to 36,000 PSI when they changed to PSI.
