I want to duplicate the Remington 405 grain Factory load in 45-70. I have some H322. 50 grains is a too brutal on my shoulder with the metal buttplate. Any hints?

Don't know how close to the factory load it is, but I've gone as low as 37.0 with H322. Factory loads with the 405 are right around 12-1300 fps. Another powder would be better suited.

I think I will go to H4198. i had a pound of h322 but also use H4198 in my 450 marlin. The h322 is pretty accurate at 50 grains but OUCH!!

My Ruger #1 and Marlin lever in 45/70 shoot the 405gr Rem bullet very well with IMR4198. Both prefer 4198 over H322.

When I ran some 405 rem factory thru the chrony they clocked only around 1300fps. No wonder they don't kick.

Loaded some up to 1700s buddys said they kick to much.

They also think my 460 gr cast loads at 1450 are to much. I don't ask them to shoot my 416.

I would use 4198 to duplcate the 1300 or so from the factory.

Try the appropriate load of SR4759, 4227 or 5744 at 1100 to 1300.

The 45-70 will not be fund to shoot with a full case of smokeless

For my Wild loads in my 45-70 I use H322 and a 405 Lazer Cast loaded a little warmer than your load and the rascal will punch you hard.

For the Mild loads I'm using Varget and a 350 Lazer Cast around 1400fps which is fun to shoot and you can do so all day long.

I would suggest looking at Varget with your 405 bullet and adjusting to get the velocity that you want with a Chronograph. You know one of those useless pieces of "thingys" that some disdain until you need one.

Exactly. The factory ammo is loaded in deference to the many older 45-70s out there. To get into that ballpark w/ H322, you want to be closer to 43-44gr

That Rem 405/1330fs load recoil level is about what a 12ga 1 oz field load produces...about 24 ftlbs of energy in an 8# gun. The same bullet at 1800fs produces about twice that.

Most people that haven't worked with heavy recoiling guns start getting nervous about 20 ftlbs or what a 30-06/180/2900fs gives you.

You might want to think about a good recoil pad, either slip on or prefit, and adding a bit of weight. That would help with the slap.

I have an NEF BC 30" bbl, 13.5# 45-120 and a factory 45-70 is hardly felt, but my friends 45-70 Marlin is down right uppity with 450 gr, loaded to the gills, T-Rex loads...and you can keep your NEF 22" 45-70 in the closet away from me...recoil is always subjective and relative to your shooter.

H322 is not really a good 45-70 powder for my taste, I don't have any data on it, although it will make the bullet go down the barrel and I like it for my 17,20 and 22 cal shooters. The best powder as far as all around shootability, economy, case life etc., for the 45-70 and 458 American is AA2460 as top dog for 400-500 gr bullets, but 4198, 4895, AA2230, AA2015, 4227, RL-7 and Varget do well...each for specific bullet weight and velocity...you just have to work up your own loads and most overlap somewhat.

SR4759's powders are also very workable for the slower loads. I have some very good SR4759 loads for my 12GAFH with 750-1000gr slugs, and I used it in a few 3.5" very heavy shotshell loads.

There are many powders that will work, some better than others. The object is to find one that fits YOUR pistol for the job you want it to do. It doesn't take much to kill a deer/antelope/bear if the bullet is placed right and a big 45 cal slug will do a lot of damage even poking along at 8-900 fs.

There is tons of data all over the net on the 45-70. A guy can go nutz looking. Steves Pages has some good data and Cast Boolits, Beartooth, Graybeard and most of the levergun forums are full of it.

Luck
