I Recently purchased a JM Marlin 1895g with a ton of brass and i'm in the process of learning how to reload and figuring out some starting loads. Problem is finding ideal components is hard right now so i'm trying to make it work with what i can get.
So far I have HODGDON H4198 and some campro 405 gr projectiles.

now the only problem I have is when looking for starting loads on hodgdon's website they don't have a load with a 405gr copper plated bullet and h4198 powder, but they do for 400 gr cast and its starting load [46.0gr powder 1,854fps 29,500 CUP] max load [50.5gr 2,002fps 39,400 CUP]

but when I go to the campro website it says for their 405 gr projectile that the starting load is 35 gr and the max load is 41gr.

I have been reading around that you should never go below starting load recommendation because of the possibility of barrel obstruction but even the max load on campro's website is below the minimum that hodgdon is recommending. I don't know what to do with this contradicting information.

does anyone have experience with this powder bullet combination?
 
Are you sure you see cast bullet when you spin 45-70 lever action 400 gr H4198 on Hodgdon site? I see a jacket bullet listed on the load, JFP

Look at the 400gr cast loads for the trapdoor on hodgdons site. If they use the same powers listed in both categories the start load for the trapdoor is how low you can safely go.

If you use h4895 you can go down to 60% the max load safely of the trapdoor loads

Imr3031 doesnt mind being loaded to low pressure either and thats a powder that would do well in both trapdoor and lever action loads.

Just use cast data in the 400gr weight range.
 
You have no worries with the 1895G as to start load pressures WRT a copper wash Vs cast bullet with H4198 it has enough safety margin to compensate. You can safely use the starting load for even the jacketed 405. The difference will be that your velocities may be somewhat higher.

H4198 is a good choice generally for cast with the 45-70, as is Rel7. They are two of my favorites.
 
If you have the Lyman Cast bullet handbook you can use their loads. No need to push those bullets very hard. For general purpose plinking, getting them at around 1200-1250 fps is nice. H-4198 is an excellent powder for that. I use magnum primers in light .45-70 loads.

One of the easiest cartridges to load. You can literally develop loads using powders from Titegroup to US869. I like 4198 for everything from "Powder Puff" to "Call the Doctor!".
 
Hodgdon’s H4198 is my *go~to* powder for 45/70. It’s a bit fast for a slow powder but lighter powder charges @ $55.00 a pound can make it last vs slower powder & bigger charges.
IMHO the heavier the bullet the bigger the recoil & heavier bullets at faster velocities makes the recoil even more pronounced. I like the CamPro loading data you mentioned. 41.0 grains of H4198 is plenty, 35-36grains would be mostly pleasant.
You might consider casting your own. LEE makes a very nice 2-cavity 45/70 bullet that comes out at 340 grains. Not too heavy & not too light. The 340 grain RNFT cast bullet behind 40.0 grains of H4198 makes 1600 FPS, a very versatile load.
 
7 grs Titegroup with a 300 gr. Campro bullet makes it shoot like a .38 special.Can't find large rifle primers so use large pistol primers and they work also.Use this load for an 83 year old gentleman in his Henry and he loves it!

Do you use anything to keep the powder against the bottom of the case?
 
I loaded some 480gr cast with Unique powder, 13 grains. If I remember correctly it gave me 1050 fps, a real nice, economical load to shoot.
