    I'm getting an H&R 45-70 to hunt in Mississippi instead of my muzzleloader. I like roundnose bullets and am settling on Hornady 350gr RN. I use alot of Hodgdon powder and thought about H4198. Any comments or suggestions?

    I use IMR 4198, I think I remember reading H4198 will give similiar performance.

    Just once, do this.

    Load up some cartridges with 70gr of FFFg black powder. Shoot them, enjoy the smoke and blast, then clean your rifle very well.

    I have an Uberti repro of the 1885 High Wall in .45-70 and the same model in .38-55. They are both great shooters and extremely accurate. I first loaded both with H4198 and I tried 5744. The 38-55 likes the H4198 and the 45-70 favors the 5744. I load to original 45-70 velocity (1300 fps) useing 405 gr hard cast lead bullets.

    Uberti 1885 High Wall fitted with Soule tang sight set, 27 gr. 5744, 405gr Laser cast bullet, Win LR primer, Lee factory crimp, OAL 2.550", fired from a bench rest = .04 X .22", 3 rounds @ 100 yds. (Everything went according to plan and Murphy was on vacation)

    4198, RL-7, 5744, 3031 and Traillboss are excellent powders to use in this sweetie. :)

    You can't go wrong with any of the powders listed in this thread, and I expecially like the 4198's. Chief

    I would question slow burning powders like
    RL7 and 3031 in a Trapdoor like the H&R. Try blackpowder, and substitutes by all means. For a hunting load, 4198 is hard to beat, as is AAC# 1680, and 5744. 4227 and H110 might also work well if carefully developed, expecially with lead bullets.

    IMR-4198 is the classic smokeless powder for Trapdoor level 45-70 loads. If you want to go hotter then IMR-3031 and Reloader-7 powders are very efficient.

    I use 5744 for mild cast bullet loads ranging from 300 to 520 grains. For hotter loads using 300 grain Nosler partitions or 400 grain speer soft points, 3031 gets the nod.

    I haven't tried 4198 or RL-7 yet.

    I will be using my 45-70 as a hunting round with most long shots around 160 yards. I think I'll try the 4198 like I planned. Thanks for the imput. I'm going to have to try the black powder as well. I'll probrably enjoy it alot.
