In Sharpe's book on handloading, there are loads for .44 Russian or Special - I don't recall which - with bullets 429565 & 429580.
These are listed as 145 grain, which is the lightest 44 boolit I've heard of.
(Other than roundballs @ ~ 120 gr)
Castpics doesn't seem to have them.
A search of castboolits doesn't yield anything.
Even the Google doesn't seem to help.
Anyone hear of, have pics, want to share their much-greater-than-mine experience & insight?
Is this a collarbutton or short WC or ?
Now I'm really curious & I know this is the place.
