I own both and don't rate them in the same strength catagory. (As do many other sources) My favorite load is 45 grains of H-4831. It is not a fast load but it shoots really well. In the Siamese I like H-4895 powder for the hot loads. How hot you can load it will depend on your bullet alloy. I think I used to shoot a 300 grain RCBS GC design over 52 grains of H-4895. It shot well and brass lasted quite a while. I'd get a good manual if I were you and start with what ever they recommend.
45-70 Siamese Mausers conversions are fairly scarce. How did you come by yours? I now have two, the last being purchased a few weeks ago from a buddy. My other Siam has killed a lot of game! ~AMMOe

I use my custom marlin 1895 gun mostly for bear over bait and have been using 405 and 320 gr hard cast bullets with 44 and 47 gr of R7--shoots well- am thinking of going to fn bullet in 350 gr but can't find any -- Speer makes a 350 --.458 for 458 win mag but doesn't make any for my gun- do you know any one who does?? Ammoe- do you want info on BBQ- I have it now.

.458 is the actual caliber of the 45-70 and the .458 Winchester Magnum. The bullets are the same caliber, .458.

Only problem is the .458 cal Speer 350 grianers are too long(won't cycle) for the lever 1895 Marlin-I had some loaded for my custom gun built on a #3 frame and guy didn't try them when bear hunting- funny story- NOW-
if you set them back enough they have much pressure and need other work- so i just removed bullets and kept them for something else. Merry Christmas
