    ...45/70 adaptors have never been a goer in a 577/450 because the the case extends into the thin neck section of the adaptor.........the Colt 45 adaptors work OK as a mechanism,but the bullets are way too small for the Martini bore.......a far more...

    I had a primer go off once broke the big hotplate on the wood stove,and the case put a dent in the roof above.The noise was deafening.Frightened the life out of me.....found out later the bullet was explosive,and I had pulled it in the vise.

    i find if you lube the mould pivots with bees wax,after a while the stuff carbonizes and sticks the sprue screw tight......no more issues............its possible a spot of loctite would do too....loctite does soften with heat,but it stays sticky,so...

    I suspect the 1 in 38 twist was chosen by Benjamin Henry in 1860 for the new 44 rimfire.For a 200 grain bullet powered by blackpowder the shallow groove and slow twist was needed to control fouling......As often happens,when the changeover to CF...

    Looks like a workable alloy is 88/12 tin,so cost would be $20 lb,with no scrap available either.The other problem I see is the metal expands on cooling,meaning bullets may stick tightly in mold cavities......As to ingots breaking apart,lead does...

    Most of the older 44-40 s have such tight necks,that bullets over 429 wont chamber ,even in thin Winchester made brass.In fact one of my 94 s is so tight a 429 bullet will seat tightly in a fired case.No sizing required.Bore size is 423-427...

    Altering 94 feed guides is a shortcut to a single shot...Very tricky,unless you have examples to copy ,or the factory drawings...And spares for the 44s were rare ,even when the guns were current.I tried to alter a 44 mag to 44-40 using a new 92...

    if you can buy a lifter and a set of feed guides for the 44-40 version,then you might have a chance.......otherwise Im sure you would end up with a single shot.

    I have sleeved chambers ,but it does leave a tiny,maybe near invisible gap,and I have always advised shooters to not use blackpowder for fear of corrosion..........Am I wrong....is a sleeve ok with the fouling?

    Will a 45 fit in a 30-30 magazine tube.?..........not a big difference,about 006.........if the rim fits,its do able IMHO,the other issue would be the dovetails in the barrel making the rebored barrel too thin in wall thickness.
