Is it really that much??? Land diameter of my S/42 is 8,82mm, a 9mm bullet is .355"...That's only .008", which means the grooves are only .004" deep...They're about a tenth of an inch wide, as far as I can tell...That doesn't seem all that much...Harbor Freight sells 10 and 20 ton presses pretty cheap...(They seem to use bottle jacks for the press)...Drill it out to .347" and then press the button through...

I wonder...Maybe a threaded ram, to turn the button while you press it???
