50 cal Maxi in a 50/70 ?

[Johnch]

A freind inherited a 50/70 trap door rifle .
He wants to shoot it .
I looked at it and it's rifling is OK but not great with some pitting .
He ask me to cast up some bullets .
He scronged 19 cases and a set of dies .
Being cheap as he is , he hoped I had a mold to use.
I have a TC 370 gr Maxi and a Maxi Hunter mold for the front stuffer .
I would cast them out of 40-1 .
I was thinking of reaming out a old sizing die to size a few to .510 or what ever the rifle slugs out to , or the max the chamber will allow .
The Maxi should hold enough lube . [smilie=l:

I looked up loading data and found a start load of 27 gr of AA5744 with a 425 gr bullet ( I have 5744 )

I dought he will shoot it much , so he wants to do this as cheap as possible .

Do you think this will work ?
Any other ideas

Does your mold cast them big enough? My only compairson is a Lee REAL bullet and the biggest diameter I can find is .510. You might have to lap out a mould to get that big of a slug.

Have to check the bore and hope .
My Maxi mold drops .510 front band , to .507 at the base .
I will load them un sized and see how it shoots .
I will not lap the mold for the few he plans on shooting .

If not big enough he will buy one of LEE's .515 molds for the 50 cal rifles

Paper patch the maxi up and you can use it.

Well after casting several different ML bullets and trying them in the 50/70 .
Best group was 12" at 50 yds
Most were 24" or more

I told him if he wants to shoot it buy more cases and a mold .
I showed him the 2 Lee sells
