    Ok guys this cartarige is new to me as I have never reloaded anything this big. I do all of my 30 06 and 7 mil and so forth, so I am not quite a greenhorn, but I am with this one.

    I will be shooting a replica 1874 Sharps in 45/70 with a 34" barrel

    Do any of you here have any good info you could pass along to me for this round.......Powder(not black powder),bullet cast or jacketed,

    If you know of a good site that has this info please let me know also.

    Thanks
    Steve

    A nearly-full case of Pyrodex RS powder (compressed) with a 405 grain cast lead bullet of your choice. Accurate, hits with authority, and fun.

    For a mild smokeless load, I like 24 grains of 2400 powder with a 320 grain gas check lead bullet. I use a small wad of dacron with keep the powder in place. This is my shoot-all-day range load with my Ruger #1 rifle. Your Sharps would hardly jump firing this load.

    If using Pyrodex your gun must be cleaned just like with REAL Black powder. Fired cases need to be deprimed & washed also,,,, Pydrodex fouling WILL rust steel & damage brass.

    My 45/70 is an H&R Handi Rifle. I have loaded three different loads for mine and my records show that all are accurate.

    # 1 - 300 grain Hornady HP being pushed by 35.5 grains of Accurate 5744 powder. This is my deer hunting load.

    # 2 - 350 Grain Berry's Bullets RNFT pushed by 48.2 grains of IMR 4064. Mostly paper shooting

    # 3 - 340 Grain Cast RNFT pushed by 49.2 grains of IMR 4064. Mostly paper shooting

    I have tried the 405 grain bullets and just did not like them. It was kind of like lobbing a rock at something down range.

    using a 405gr lead bullet no gas check with 43-45 grs varget.

    acceptable CUP pressures and velocity......about 1400fps.

    i have read of folks using IMR 3031, RL#7 and even trail boss.

    hope this helps.....

    Your 1874 Sharps is a relatively weak action. Do NOT use loads intended for the Marlin 1895 or Ruger No. 1 in it.
    Maximum loads should be considered as no more than 18,000 Copper Units of Pressure (CUP). It would be best to stay well under that.
    I have a Marlin 1895, and a reproduction 1873 Springfield "trapdoor," both purchased in 1977.
    A good load for my Springfield has been the Lyman 457193 flatpoint cast bullet, which is about 420 grains when cast of wheelweights or equivalent. I load this over 37.0 grains of IMR3031. I size the bullet to .459 inch and lubricate with the typical beeswax/Alox lubricant mix.
    If someday you decide to get a Marlin or other rifle that can take higher pressures, assemble those loads with nickel-plated cases. Use brass cases for the Sharps. This will prevent you from dropping a high-pressure load in that Sharps.
    Years ago, I'd take a red Magic Marker and run it up and down the brass case, of the loads I assembled for the Marlin. Back then, no one made nickeled .45-70 cases.

    One final warning: Never use a load posted on the internet without first checking it against the website or reloading book of the projectile or powder you're using. This includes the load above, that I just gave you.
    There are all kinds of wild claims and excessive loads posted for the .45-70 by folks who have absolutely NO access to a ballistics lab to measure pressures. The manufacturers of bullets and powder DO have labs that can measure pressure.
    Some folks like to push the limits with the .45-70. I like my fingers, eyes and guns too much to do so.

    I also like Varget in my .45-70 Shiloh Sharps. I use Trailboss in the Trapdoor, gives a nice easy on the shoulder load.
