Alliant 2400?

[Longhunter7]

I came across a good deal on reloads with 23 gr. of 2400 and hard cast 450 gr. flat point bullets. I can't find any data to help me determine the velocity and if that is a safe load using pistol powder? :?:

for 500 S&W Mag?

Dont shoot mystery reloads. Its not safe. Why risk your gun or more to save money? my over valued two cents

First do you know who reloaded these and how much do you trust them. Second I would pull a bullet and verify the powder weight before I did anything else. Third more info is needed such as caliber, over all length etc. I only shoot reloaded ammo from a know source that I trust. Since I reload myself that does not happen often but occasionally I will try out a friends gun that he reloads for.

Sorry about that! I meant to mention the loads are for a .45/70 Marlin lever action!

[JonB_in_Glencoe]

45-70 in a Marlin, eh. ...If I was gonna shoot those in my gun, I'd look up some data in a few different manuals.

BUT...judging by these two threads, you are 'Probably' OK with 23gr under a hard cast 450 gr. flat point bullet.

You threw a curveball by me, when you mentioned pistol powder.
technically, 2400 was designed for 22 hornet ...um, ur, maybe that was 22 Hornet was designed for 2400? :veryconfu

There is some published data in this manual for a 340gr cast boolit.

PS, I took the time to post this, mostly because they list a duplex load for 405gr boolit...a small dab of pistol powder under 60+ gr (enough for compressed load) of wholly Black (FFg) :shock:

[Longhunter7]

JonB,
thank you for the links! It appears that A2400 is a popular powder even for Trapdoor rifles!

[Longhunter7]

JonB,
The reason I mentioned A2400 as a pistol powder, is when I looked up load data, all I saw was pistol data. It was't listed as a rifle powder!

[Char-Gar]

The load would be a good and fairly low presure load for the 45-70. That said, never shoot somebody elses reloads..never. If you don't load em, don't shoot em.

[NSB]

I will never use anyone's reloads unless I personally know the person well enough to trust their ability to reload good ammo. Unknown to me and it's a no-go. That being said, I use 2400 in the 45-70 quite a bit. In fact, some of my best loads are shot with that powder. I don't condone using those shells, but the load's not "hot" at all.

[fatelk]

It sounds like 23gr is a safe enough load, so long at there's not a couple in there with 46gr instead, by accident (or even one).

[Wayne Smith]

Pull them down, save the components, and reload to your hearts content. That's what I would do with someone else's reloads unless it was Erv, my best friend, engineer, whom I taught to reload.

Yeah the golden rule of shooting is you do NOT shoot other peoples reloads, unless they are lic & bonded for your protection. Sure it is supposed to be 23gr of 2400, but???
