    The trick to take the action out is to hold the muzzle up,this should make the extractor lay back and clear the cut...Remove the retainer ,split pin comes out the right side ,open the action ,index finger thru the trigger guard ,thumb against lever...

    Is this gun a Cwlth Cadet or a later BSA?.....all the later BSA s have a hole in the back of the reciever in line with the bore,so they can be cleaned from the breech .....Its also a very common mod when a Cadet is converted to a HP cal.

    On thing I do know cleans brass is a mix of HCl and methylated spirits ....I used it years ago to clean pennies of tarnish ,it does that spectacularly well ,but as I have learned in the years since ,its hard to stop further corrosion with HCl.....In...

    john.k replied to a thread Breech Strength in Muzzleloading.

    There is a drill that will drill very hard steel......solid carbide rod with a pyramid shape point.Run at high speed ,it basically melts out the steel and pushes it aside,not suitable for deep drilling......If these are not suitable ,then I suggest...

    Before grinding a tool for square thread ,try to find a decent brand of HSS....IMHO ,a lot of chinese HSS sold by hobby shops tends to crumble at sharp edges,and is useless for Fagersta,Poldi stahl,Jessops,etc.

    A good deal of misinformation here on Cadets ....if the rim recess is deepened to 32/20 specs ,any Cadet will take a 32/20 ...and most ,if not all the 1908 delivery Greeners will take a 32/20 case without any alteration whatso ever...No cadet ever...
