1862 Needham Conversion Rifle .58 Berdan

[7up]

Hi all.
Picked up a real nice New York 1862 dated rifle with side opening breech. This is one of the nicest guns I have picked up.
Does anyone have any loading tips for the (assumed) .58 berdan cartridge please ?
I have (not) in my possession :

24g brass hulls
Brass tube cutter
LEE .575 minie mold
Some Swiss no4 black
(No dies of that size)

Cheers

Seems like Croft Barker has written an article or two on these things maybe is the Single Shot Exchange magazine, one of his books, or both.

Hello thanks for the reply.

Managed to get a cartridge together using 24g magtech brass.
Run through 577 sizing die, however wouldn't fully chamber. So I gently bumped the shoulder using 577/450 die and it goes in.
Issue I have is the firing pin strike is too shallow. So I am guessing the rim is slightly to thin.
I have seen 50-70 brass, do they have thicker rims ?

50-70 may not neck up to 58???

Hello - I managed a workaround by using rubber washers, which does the trick

I have One and shot Mine . The Cartridge Is not 58 Berdan. . The cartridge Is 58 center fire Musket . . Thats what mine is In. 28 gage will work but you will still have to reduce the Neck.. . I use a sleeve as a Die just enough to reduce the neck slight .
I went By the Original I have. But even The original are Tight.
. This is a Trial and error
