Default Powder loads for 45-70 in Marlin 1895

I've just started loading for 45-70 to be used in my Marlin 1895SBL. I've already loaded up a few rounds with Trail Boss under some 350 lead bullets which should be totally good to go in my rifle. My question is about "normal" loads with 350gr Hornady jacketed bullets. I plan on using H335 as it appears to produce the lowest pressures still with decent speeds(at least of the powders I have). Intended use is recreational shooting, so I'm not interested in anything crazy hot.

All my books and Hodgdon's website break the data into three categories, old trapdoors, lever actions and modern designs. The Lyman and Lee books both say max pressure for lever guns is 28,000 CUP, listing H335 at 51.2gr-54gr. Looking at the Hornady book and the Hodgdon site, they list the max pressure for lever guns at 40,000 CUP, listing H335 from 54gr-60gr. Throwing an extra wrench in the works is the Sierra book, they don't list pressures at all, but they list H335 at 57.6gr-63.6gr for the 1895 Marlin.

So, I'm not sure to go with these. First and foremost, I'd like to know what is the realistic max so I can stay away from it for sure. Secondly, what have you guys found to be a good load for a 350 gr jacketed bullet that for sure works safely in a Marlin 1895?

Thanks!

In my 2nd round of googling I discovered that while the marlin can indeed take 40,000 CUP, it would be very unpleasant to load to that level. It's also very hard on the brass. Good to know!
I'll keep my max loads well below that level.

loads I have used for my 18'' 1895 for 100 yard shootin are

300gr JHP / 46grs 3031 / cci #34

405gr JSP / 42gr 3031 / cci#34

I never loaded any 350gr bullets but in the middle with 44gr of 3031 should work well .

Thanks Rick! Unfortunately, I don't have 3031 at the moment, but it does seem to be one of the top rated powders for this caliber. I may end up picking some up.

This sight may help you out with other powders.

I had a whole 8lbs of 8208 XBR , and after selling my 308...wasnt using it for much else. I load a LOT of 45-70 , so I went to Hodgdon's website ...and sure enough they had XBR loads there for the 45-70.

My guide gun loved Hodgdons maximum XBR load with the 350 jacketed RN , still only 36,200 CUP...and since it's a compressed load you get zero powder shifting in the case.

I also had great results with Benchmark , also here in Hodgdons data for 350gr jacketed RN data.

Oh nice! Glad to hear it deal with the higher pressures well. I know everyone's experience is different, but would you equate the felt recoil(form your load) to something like a .30-06 or is it more in the .300 Win Mag category?

I ended up loading 5 rounds each with 52gr, 54gr and 56gr of H335 under a 350gr JFP. Those should give me a good idea of what I'm willing to go with for a recreational load.

I noticed that there is space left over in the case between the powder and bullet. Does 45-70 suffer in that condition? I know some people put wadding material in these big cases with lighter loads.

Lastly, do you use a magnum or regular primer?

I like 35gr of BLC-2 under the Oregon Trail 405gr FP bullet.
Shoots great in both my Winchester 1886 (new model) and the Marlin...

Here's a 12" saw blade shot with the 405s at 100yds:

Damn, I don't think that saw blade will be cutting clean miters anymore!

The 350gr lead bullets I got are from Oregon Trail. Have you had any problems with barrel leading?

I've never shot a jacketed bullet in my 1895.Typically load 460gr or 520gr hardcast w/GC. Get about 1600fps out of the heavier bullets.

Marlins come with pretty crappy recoil pads, if you're going to shoot stout loads regularly I recommend getting a pre-fit Limbsaver or fitting a Pachmayr Decellerator.

Damn, that has to deliver some serious energy!!! Are you shooting those giant elephant creatures at the end of Lord of the Rings?

Luckily, the 1895SBL comes with the Pachmayr pad on it already, so I'm gtg in that area.

Brush hunting.
Full penetration from end to end regardless of bone encountered.
