2400 was originally made for .22Hornet. I would have thought it would be a bit fast for 45-70.

 

Seems fast for 45-70.
Bet the staring pressure would be pretty high.
Also I doubt it would even give 50% fill on teh case.

 

Sierra has it listed for the trapdoor, 1886 Winchester, & Marlin...

Starting for the Trapdoor is 24.5Grns with a maximum of 29.7
for the Marlin it starts at 36.9 and with a max of 40.9

Before someone blows up their Marlin and gets seriously injured, can the inaccurate max load of 49.5 grains of 2400 be changed to the correct MAX load of 40.9 grains?

 

I would be very careful about putting 49grns of 2400 in a 45-70 case as this sounds like a recipe for disaster.
25 grns would be the most I would even think about.

 

I have a Lyman 46th Edition that has a lot of listings for 2400 in the 45-70, for several different bullets (of the day). Most are for cast bullets, but a few listed for the lighter jacketed bullets.

I don't own, or load for, the 45-70 so I have no personal hands on experience myself. My personal experience in loading rifle cartridges is limited to 30-30 win, of which 95% consist of cast bullets with A2400, AA#7 or Unique.

Have to work the load as normal.

 

No, I like blowing up and loosing an eye and teeth. lol.


MY Bad.
I actually mistook Viht N120 as the max for 2400.

49grns of 2400 would be a big disaster.
Nice catch Bassetman.

I guessed that's what happened. That fast of a burning powder makes me nervous enough in large quantity, that's why I looked it up. Just didn't want anyone hurt. I wish you good and safe shooting.

 

It bothers me that they list the 1895 Marlin with the Ruger #1 which is supposed to be in a league of its own. If memory serves me right, I am currently using Benchmark with the 300 HPFN but I do have a big jug of 2400 I need to use for something so maybe I will try low and slow and work my way up later in the year.

 

Try using your 2400 in a .357mag. 13grns is a nice heavy load which pushes more than it hurts.

 

In that listing of Sierra, they used the Marlin 1895 as the test rifle.

Agree with you that the Marlin should not be listed with the Ruger.

 

I load a lot of 300 Gr jacket bullets. In my 45-70’s levers mine like IMR 4198 & 50 grs and OAL of 2.542 with LRMag primers

 

Use 27.7 grains of 2400 with Berry’s 350gr plated bullet. 3 five shot strings over chronograph, averaging 1537fps. Get approximately 2- 2 1/2 inch groups at 100. Able to ring steel at 309, 400 and 500 yards, size of deer chest ( 20 x 30 inch).

 

Nice,
I have some of that Berry’s plated bullets.

Want to push the 300grn Sierra bullet around 1900 with the 2400 powder. Going to use that combo for elk this year. I know the 45-70 is a 200 yard gun maybe 250. Just wanted to get a feel for what people are getting for accuracy.

 

If it ain’t listed do not use it

 

One can be safe and experiment. Otherwise, we would not have the vast array of guns and calibers available today.
