I know my way around a cartridge

I've been loading my own for many years. I reload for every rifle I own. I won't mention all of them here, but many calibers. I would like to get Everyones thoughts on the 4570. Load data, different types of progectiles, ect.
 
Ahh but not your way around the firing line.

That is a question for the Reloading section.

Much better Title would be something to do with the 45-70
 
Powder: IMR 4198, Rel 7

Bullets: 350 gr to 500 gr cast with a BHN approximately 10.

I don't believe in hard cast.

If you shoot the 500 grn cast bullets, hang on to it.
 
My own experience with the 45-70 Government have been it all depends on which rifle I am loading for. I have an old Springfield Trapdoor which obviously does not have the action strength as many of the newer lever guns. Using 300 grain bullets unless I kept my loads light at 100 yards I was shooting a foot or more above my point of aim. My favorite bullets were 400 to 500 grain using powders like IMR 4064.

The Marlin 1895 I liked 400 grain JHP bullets using H 4895 about 54 to 55 grains and IMR 4198 around 37 to 38 grains. I leaned towards the H 4895 as it would come close to making a full case with the loads I used. The lever gun was used primarily as a hunting rifle and thus I liked the JHP bullets.

Again, it really depends on the rifle action what you can do with the cartridge and the intended application. Since I don't cast just about everything I load is FMJ or JHP but I have used cast bullets I bought a few times.

I really like my Springfield Trapdoor carbine in 45-70. Started out w/ IMR3031 and a 300gr. lead cast bullet, then switched to BP w/ the same bullet. Boom!

You don't say what your platform is or the intended purpose of that platform......in 45-70, that makes a huge difference in powder, charge rates and what projectile one is using.

I started reloading 45-70 for my younger brother who just bought a Marlin Guide Gun last year to hunt deer. I've been working on loads with Hornady's 325 gr FTX and their 350 gr JFP. I personally don't see a need for anything heavier for whitetails.
 
I load several rounds for my marlin 1895 guide gun. Depending on bullet dictates my powder. For the 325 gr FTX, I use imr 4198. I shoot Sierra 300 gr hp as well and use 4198 for that. I also load 330gr "gould express" lead hollow point using 20:1 casting lead. I shoot that at trapdoor velocities using unique.
 
. I shoot Sierra 300 gr hp as well and use 4198 for that..

Was wanting to try those too, but they are back-ordered everywhere I look....even on the Sierra Website. Nosler has a coupla interesting Ballistic Tip 300 grainers meant for hunting with 45-70, but like the Sierra's, they are backordered everywhere, and also on the Nosler Website. I have yet to find anything from Speer available either. Like other calibers, bullet manufacturers shut down the manufacture of low demand bullets so they could up the production of the higher demanding bullets in their line during the shortages. Seems they haven't done much to improve on availability of 45-70 projectiles. I don't really like spending the big bucks for the "boutique" stuff either, altho they are available and work. Just for Whitetail deer, they aren't really needed.
 
45-70 reload

My absolute favorite cartridge to reload.I have a JM barreled Marlin cowboy with the 26 inch octagon barrel.I cast 3 bullet weights for it and keep every piece of brass I own loaded for it at all times.Just something about them brings a smile to my face.I have loaded them to higher so called Marlin pressure and to standard pressure as well.It gets a bad rap by some for not shooting flat but with practice and some studying of ballistics it may surprise you.When it connects whatever you shoot with it goes down.When it was introduced the army wanted a round that could drop a horse at 500 yards because of the Indians standing in the way of western expansion.It was also used on the American bison to slaughter thousands of their hurds.
 
As mentioned, the rifle you're loading for matters. You cannot use the same data tested for a Ruger No. 1(AKA a Modern rifle) in a TrapDoor(TD) Springfield(includes H&R Hand-Rifles and the like) or a Lever action. And the original BP load for a TrapDoor rifle was not the same as that for a TD Carbine. 70 grains of BP with a cast 405 grain bullet out of a 6 pound TD Carbine hurts to shoot.
Otherwise, your manual will have loads that are safe for a TD or lever as well as near .458 Win loads for a Ruger. The .45-70 is loaded a great deal like a straight walled handgun cartridge like the .45 Colt or .44 Mag.
