Interesting experience with 2400 today...

Keep in mind that 2400 was reformulated at some point. Mr Taffin reccomends dropping to 21 grains of the reformulated 2400 for the "Keith Load" in 44 Magnum. I'd probably drop my charge by at least .5 grain when I tried the new powder.

The powder used was from an old square can, don't know when they discontinued those, but it was probably at least 40 years old. I am pretty sure my 'new' container, at about 6/7 years old, is older than the reformulation as well, but I agree it would be prudent to drop it back a bit and work my way up carefully.
