Boring the breech

[Frmrspec]

Did anything ever happen with this idea? The other fix that I thought off would include machining the hammer catch and the main arm to allow a longer pump stroke, mixed with a longer bolt

No, nothing yet. First gun I've bought new since high school, so I'm going to finish some other projects before it goes under the knife.

Could the body just re-bored and threaded deeper in so the ball is loaded into the end of the barrel then any Spyder threaded freak barrel would work without the insert sticking out? Or better yet settle for Autococker threads then the barrel availability sky rockets?

Not enough meat between the tubes, unfortunately. Maybe with a skinny Spyder barrel like an old J&J, but even that would be marginal.
A custom cut-down Freak back is probably the best route so at least there are options for fronts, but my plan is to bore and port the stock barrel, and maybe one aftermarket, and just keep those with the gun. Not too different from having an old Sterling with its weird threads.

You're inspiring me 😅

When I get mine going I'll bore the breach and only bore the barrel just deep enough.
I'm gonna have to do the same thing for the phoenix anyway 😅

Just to put this out there...

Last weekend I shot a brand new STP, and a janky old Bronze. On the bronze, i had plugged the feedneck, moved it forward, and made a longer bolt so it chambers straight into the barrel.

Using the same barrel throughout the day, the janky sterling was the better shot, by far. I convinced myself it makes a difference. Now it's just a question of whether I bore it for an insert, or cut the whole top tube off and throw a T2 top half on there.

Not a whole lot of material between the upper and lower bores to drill/tap and hold securely.. that was the big reason why custom lower tubes were made to accommodate a T2 upper tube....
