I know there is lots of info to be found by searching, but a couple things I can't find.
1) are the Hornady 350gr. RN safe in a tube magazine (1895G)
2) all kinds of conflicting load data for this round using H4198, what is the true starting point and max point.

thank you in advance for advising
 
The Hornady 7th edition includes data for the 350gr RN in the 1895 Marlin loading data sub-section. They have data for IMR 4198, but not H 4198.
 
350 GR. HDY JRN Hodgdon H4198 .458" 2.540" 48.5 2036 32,200 CUP 54.0 2191 39,300 CUP

The above a copy from the reloading table at the site below.

Translation Hornady 350 RN H4198, from 48.5Grains (2036fps) to 54.0 grains (2191)

NOTE, DO NOT USE IMR 4198 POWDER WITH THIS DATA!!!!

The corresponding Max load with IMR powder is 50 grains! (2131fps)

The 350 RN is safe in the Marlin 1895

The data is conflicting because everyone has different ideas as to how much pressure a Marlin action can take. Hornady as a member of SAAMI has to keep all their published loads for the 45-70 under SAAMI maximums. Hodgdon powder on the other hand however lists 45-70 loads to the same pressure as the 444 Marlin and 450 Marlin which are a fair bit above SAAMI maximums for the 45-70.
 
i do not know where to get Hornady bullets like those you want. I do know that the bullet barn has cast bullets in the weight you are seeking.My book says for a 350gr. bullet...H4198...start 50.5 ......high end 56gr, but only for modern guns which I take it you have.

As they're side by side on the burning rate chart I didn't think there'd be much difference in the charges listed for each. You mentioned "The corresponding Max load with IMR powder is 50 grains!" Where abouts was that listed? Just asking as I couldn't find it. In the Hornady 7th edition, for use in (1895 Marlin) with either their 350gr RN or the 350gr FP they list a maximum for IMR 4198 of 45.3grs and with H 4198 48.4grs.
 
"...think it was IMR 4198 in a Hogdon H4198 can..." There's no way to tell just by looking at it.
Data for IMR4198 starts a grain or so more than H4198. Definitely not interchangeable. Although max pressures for the 'H' is higher than the IMR. Pick one or the other and work up a load.
Hodgdon's site lists Trapdoor loads and loads for modern lever actions. Which lever action doesn't matter.
Don't mix the two data sheets. Mind you, it's not as big a deal if you use Trapdoor loads in a lever action. The other way will wreck your day though. Max pressures are nearly 20,000 CUP less for a Trapdoor.
 
i think you need to back up a minute.......never, ever buy powder that is not in it's orig. factory container or at least properly marked bulk containers from a reputable retailer(such as Higginsons)......I would pitch that powder out as you do not know what it is, buy some new powder for your reloading and do your research first from loading manuals. They will tell you whether a certain bullet can be used in a lever gun. It sounds as though you are inexperienced at reloading and I think you are into this in a way that could be dangerous to yourself. Study some manuals and/or watch someone who is experienced in reloading. The idea that it is either H or IMR 4198 is not comforting as it could be H or IMR 4227 or some such.

Gotta' agree. Especially at gun shows, we all have the tendency to bargain hunt and dicker but where powder is concerned that 'cheap stuff' could end up costing you much more in a long run.
 
I certainly agree, also. Probably the most common cause of a blow up is the use of the wrong powder. That's why I consider the most basic rule of reloading is to have only one can of powder on your bench at a time. And as was just said, don't ever buy powder except in its original, sealed container.
 
My load is 48 grains of RL-7 under the 350 grain Hornady FNSP. I have loaded up to 50 grains of the same powder for a buddy for moose, thats a real stiff load. The 48 grain load is good, but the issue recoil pad has to go. Also ditch the factory lever unless you use shooting glove, otherwise, it tough on the knuckles.
