    California has now passed a law -- previously a DFG request and a forthcoming DFG regulation anyway -- requiring non-lead bullets in part of the state.

    Anyone ever use a copper hunting bullet of any kind that worked in a 1:48" barrel?

    Can anyone name some redeeming qualities that California has? I'm having trouble finding reasons why I should pray that it doesn't sink into the pacific...

    Maybe try casting bismuth bullets?

    To answer your question (as opposed to ranting against California, which is a tempting but unhelpful response):

    There is no readily available substitute material for lead to use in making bullets, round or otherwise. Solid copper or copper jacketed bullets will destroy the rifling in a black powder gun in very short order.

    eventually it will probably be taken by a quake, it's to bad all the people that screwed it up won't be on the leading edge.

    you might consider a sabot with a copper pistol bullet (I think Barnes makes). I shot some sabots out of my .50 1-48 and they do well, but I prefer the Lee REAL slug as I'm working on dialling it in for hog hunting.

    What about jacketed PowerBelts? Does only the plastic base engage the rifling?

    Thanks. That's what I was looking for. Barnes and Knight sell sabot rounds with solid copper bullets. I just haven't shot anything like that in my 1:48 twist .50.

    What weight bullet were you shooting?

    Also, I've seen guys wrestling with sabots in a muzzleloader. Is there a trick to loading them, apart from using a hydraulic press?

    Yes, the sabot engages the rifling with the jacketed Powerbelt; the bullet does not.

    And that, of course, is the answer - a saboted copper jacketed bullet.

    I have to admit to a lapse in conciousness here - I jumped immediately to a copper ball or mini that would engage the rifling.

    What day is it? How long was I out?

    There's no sabot on a Powerbelt.

    There is a plastic base that (I think) functions like the base of a Minie Ball. The Whole bullet does contact the barrel, but I'm guessing only the lands.

    The plastic base on the powerbelt acts as a gas seal,and holds the powerbelt in place untill the gun is fired.The powerbelt then expands and makes contact on both the lands and grooves of the barrel.I have found two powerbelts in deer I have shot and it is easy to see what happens.

    I don't know how many copper plated bullets it takes to destroy a barrel, I've fired at least 200 in a TC Hawkins with a Green Mountain barrel and it looks the same.

    ArmedBear you can find a lot of info. on sabots at this site: Rand Wakeman on Inline Muzzleloading.

    You have the Green Mountain 1:28" or a 1:48"?

    I have a Green Mountain 1-28 barrel,they make one that comes with sights,ramrod ready to go,just pull the wedge out of the TC Hawkins,drop the GM barrel in,start shooting.No fitting or changes to be made.

    The TC 1-48 original barrel shot 15'' to the left at 100yds.The rear sight was almost falling off the barrel to correct it.Tried different loads nothing worked.I guess I could have sent it back to TC,anyway no problems now.

    The length of the bullet will determine the required twist. Stick with a short, blunt bullet and you should be OK. As mentioned, a saboted sub caliber copper should do the trick, if allowed by regulation.

    GunTech-

    I'd thought it was the weight that determined the required twist. I guess that's true within a certain cartridge (e.g. .223) where the weight determines the length, but I wasn't thinking that through.

    Anyway, you say "blunt", but what about, say the Barnes MZ, which has the center of gravity and weight distribution of a blunt bullet, but a plastic spitzer tip.

    Do the aerodynamics of a bullet influence optimal twist, or is it just the weight distribution?
