24 gr 2400

[gman]

Have shot this load before in my 1895SS but wanted to chrono. I decided to size to .461 from .460 due to the case mouth expansion on fired cases. When this rifle was new I had an old timer give me the first cast bullets I ever shot from this rifle. Typical groups were two shots close or touching with the third an inch or so away. That old timer is long gone and unfortunately I never got to learn from him. So, until this 24 gr load of 2400 Fed 210 primer and the BRP 462-420 GC lubed with SL-71B I haven’t been this close to duplicating that performance. Bhn of bullets were 12. Chrono data on printer paper on target.

24 grs. of 2400 is my FAVORITE load in my own 45/70, Siamese Mauser sporter ! !
It is a killer on White Tail deer.
Mine is the plain base Accurate 405 gr. V.

I hope to test it in about 10 days once I get up to my friends place in Mississippi. You can bet I’ll report!

I use a 420 gr plain base from a long ago Lee group buy with 24 gr of 2400 as my standard load in the Marlin 1895. Shoots better than it should, way better.

The accuracy load with the same 405gr as Ben mentioned in my Marlin 1895 is 42gr of IMR3031.
Very nice shooting Gman!

I got to try that load.

Thanks Waco! I’ve shot that old girl from mild to wild. Shot a whitetail buck once with a 385 gr cast hollow point on top of a heaping dose of 3031. Looked like he was hit with a freight train. My shoulder likes this milder load.

I have shot a few deer with my Marlin. First was a 425 RD bullet on top of a bunch of 4895. I no longer feel that is required as a 410 gr cast bullet at 1350 fps is going to do all I need.

Gman, That is my favorite load. With the original Lyman 475193 Marlin bullet, not only is it accurate, but also safe as a top load in a Trapdoor. Shot many hundreds in the CBA Military Matches over the years. Shooting like that you can take it hunting anywhere in North America!

Ben, that’s a great photo of your cast boolits!

 

[fiver]

as soon as I seen the header to the thread I immediately thought 45-70.
I use the same amount on top of a 435gr LEE T/L mold.
I'm trying to figure out how to powder coat this one and still get the gas check on it.

I started with Lee 405HB RNFP and 38.5 grns of IMR-3031. Worked/works great. My hunting load. Peeps and my old eyes are about 2-2 1/2" at 65-75 yds. VERY adequate for my brushy deer woods and preferred short range shots. Chrono's ~1325 fps and flips a small deer at 85 yds. I do have some worked up with 40.0 grns because I am lazy and it is a simple one scale slide setting!

Having said all that, I now also have the RD 300 and 350s. And plan on starting with the 24/2400 load. I don't think I have seen anyone have bad luck with it. Will be used in my Marlin and also my yet to be shot Husquvarna 1871 custom 45-70.

2400 is no slouch in a 30-30 either. Mine likes around 16 gr with a 165 RD bullet.

Kinda odd that I rarely use 2400 in handguns but it is a go to powder in rifles.

 

[KHornet]

IMNTBHO, I believe that the load of 24 gr of 2400 behind a bullet of 400-425
gr. in a 45-70 will within range be adequate for any game in the Lower 48.
Have also found that it seems to be pretty consistant that the first 2 rds on
paper will be close or touching, and the third one out a bit. Have had a couple
of 3 shot cloverlears, but only in fairly hot weather. Find the same thing with
375 H&H with cast. The 385 Lyman also shoots very well with 24-26 gr of
2400.

I went on a tear with 2400 a few years back and started using it in just about everything I have.
the 223, the 38 special, all kinds of everything just seeing what it could do.
it's not what I would call a perfect powder it has some minor faults in places but it sure did cover one heck of a lot of applications.
if it were a bit easier to ignite it would nearly be a one stop powder.

 

[KHornet]

Tend to agree with you Fiver, and have shot it in just about all
rifle ctgs, and most of the straight walled revolver ctgs, but
not in 38S.

That's exactly what I did a couple years ago, except with True Blue. True Blue is just a tick faster-burning than 2400, but shares most of the same characteristics across a wide range of bottlenecked/straight-wall cartridges and reacts similarly pressure-wise when mass is stacked on or powder charge weight is increased incrementally. My only complaints about TB is that it requires a little more pressure than .38/.45ACP/.45Colt standard loads develop in order to burn cleanly, so there's a little "pepper" in the bores and will really dirty up a 1911. The difference between TB and 2400 in the low-pressure loads really becomes apparent when looking at SD, though. TB burns very consistently even way below its optimum pressure range, kind of like RX-7 which will leave a huge pile of empty kernel shells behind, but still turn out single-digit SDs.

I am about to look at RL7 as a near all-rounder... Espec for cast. But see a lot of apps for jackets, even down to 223...

Have you ever put the gas check on then powder coat? The gas checks stay on! That's for sure! Lol!
