Hi Buckstix,
As per my post, I don't think it works anymore.
I do have the same pushbutton. The 3rd bite is not a Greener bolt but a doll's head and a flat bolt as can be see on the published picture.
The early loadings involve a 232 grain bullet, switched in 1898 to a 198gr bullet.You should start at 232 grs.
My bores are 8.30/8.0mm (.327/.315) 4 groove. The grooves are very deep indeed. My WWI era bronze bullets measure about 8.28mm i.e 0.326".
If a .323 bullet is used, it should be soft to have a chance to bump up.
Just my $.02!

Please measure your bores!
