    My friends father inlaw is wanting me to reload some 45/70 govt. loads for him. Not a problume usaly, but here is my question.
    He will be shooting it through his old sharps.
    This is not a madern sharps, it is an original. still in great fiering order,well taken cared of all thease years.

    I don't want to damage the rifle.
    I was thinking soft lead cast bullets, I know it will cause leading. but if I use coper jaketed bullets could they not damage the rifle. being as old as it is?
    It is in great shape. But i just want to make shure.
    Any thoughts?

    405 cast lead bullet on top of 50 grains of 2F black powder, with something on top of the powder to take up the space (cardboard spacers [what the Army used], 410 shotgun felt wads, grits). I'd be much more worried about smokeless powder hurting the gun, than I would a jacketed bullet.

    I used to shoot an old remington rolling block Dale. Just use any cast 405 gr lead bullet and trailboss. Run them at 1200-1400 fps and it wont hurt the rifle.

    Other than that, BP, as Alpo mentions, is the only other way to go

    those single shots are not at all COAL sensitive. Just seat the bullet tot he cannelure and use a charge of TB that fills the case to 90% capacity. prolly be around about 12 gr or so right off the top of my head for a 405 gr bullet..

    If you load them with BP, don't forget to remind him to run hot water through the barrel after shooting. Potassium Nitrate can only be disolved with water. An oiled patch alone will not clean it. Water first, then oil. I know it sounds obvious, but it is easy to forget when you are used to shooting smokeless.
