2400 burns a little fast for either max velocity or best accuracy in most 45/70 rifles,
I would strongly suggest useing H4895, RL-7 ,IMR-4198 or IMR-3031,
I think youll find that you can get higher velocities at lower peak pressures and better accuracy also.
I would also suggest that you cast your own bullets, youll save hundred of dollars and get to shoot far more in the long run,heres a few tips
buy the lyman cast bullet manual
NEI makes EXCELLENT MOLDS
the bullets MUST be sized about .001-.002 over bore size
the bullets with gas checks tend to be more accurate
the bullets in the 350-440 weight range tend to be more acurate
the bullets should be seated out to the MAX length that will function in the gun.
bullet speed over about 1700fps tend to be less acurate in most guns
IMR 4198,RL-7 and H4895,and IMR3031 tend to be accurate
the bullet lube you use has a big effect on accuracy
the bullet ALLOY has an effect, on bullet accuracy, 94% wheel weights/6%tin works ok for most loads
bullets like these proved VERY accurate in my 45/70 marlin WHEN TESTING FOR THE ACCURACY, NOT the MAX VELOCITY was the determining factor in how fast you push them, and what loads you used
BTW heres the bullet lube formula Ive used for years with total success
5 lbs bees wax
5 lbs paraffin
2 lbs MOLY AXLE GREASE (Chevron Moly Greases EP)
1 lb MOLY powder
