    This is a Rifle I built 5 years since.The castings for the metalwork are from a Kit gun replica of the Greener GP Shotgun once retailed by Brownells.The castings where in the rough and required filling and polishing.it was necessary to make some parts that where missing.The Barrel is a 20 bore lined with a liner made from a 8mm Rolling Block Barrel.

    It was necessary to make a Chamber Reamer an Extractor and a cocking Pawl.The Timber came with the Kit,The butt plate was missing.I still have the 12 bore Barrel in the white.The front lever on the frame is for releasing the Take Down Barrel.

    The Tang Sight is own made but the eye piece is from an original sight.The Rounds shown are for comparison 50.70, 45.70, 32.40.The coil is my Blow Tube since small Calibre black Powder Rifles foul up quickly.

    Love the 32-40 round. Easy to load and pleasant to shoot. I have a nice old Maynard 1882 in that caliber. Really fun to shoot. Nice rifle you have there.

    Very nice work. I have two bone stock Martinis, A 577-450 and a Cadet. That gun of yours is sure purtier.

    Col4570, I like your rig. You and me think a lot alike. I used a 20ga. barrel also and built a 45-70 using a TJ's liner from Track of the Wolf.

    I used a BSA MkII action which is a little smaller than your Greener and it came out a little on the light side (under 7lbs.) so it's tad punishing to shoot. I just stick with black powder loads although I did shoot some smokeless loads through it with good results.

    How does that takedown lever work? Does it just pinch the action together to tighten up on the threads?

    Here's mine.

    And my paper patched black powder loads.

    Rojelio,The Take down is as you say a pinch type ring.On the front face there is a groove that comes to a stop.On the Barrel there is a boss with a small projection as high as the thread pitch.When the Frame and the Barrel are fully together the projection comes to a stop in the Groove.To Remove the Barrel open the Falling Block to push the extractor back,Turn the Locking Lever about 1/2 a turn and unscrew the Barrel.

    Thanks Col4570. I see how it works. That's ingenious. Thanks for the pictures and explanation.

    Spectacular, sir! It's like "Day of the Jackal", filtered through 'Quigley Down Under"!

    That is pretty cool!
    Did you say you built it out of a Greener kit? As in one of those really cool riot guns that originally took the bottleneck 12/14 gauge shell?
    One of those in 12 or 20 gauge wouldn't have been too bad either, but it doesn't look like anyone would have the right to complain about the way you chose to go with that one.

    It was a copy of the Greener GP (general purpose) 12 Bore Shotgun In Kit form.I bought it as rough castings and made some parts that where missing.I still have the 12 Bore Barrel in the white and Forend timber.I have two of this type of Shotgun made by Greener they where once popular with Farmers as a robust carry on the Tractor gun.They can be picked up reasonably cheap here in various conditions from rough to mint.The Martini Action is very close in design to the Martini henry 577/450 rifle,in fact some parts will fit both the GP and the MH.

    Those are pretty cool!
    It's been years since I've read about the Greener falling block shotguns. I hadn't thought about them in a long time until you mentioned them in this thread. I wouldn't mind having one of the riot control versions rebarreled to use regular 12 gauge... I swear I'd hunt with it if I had one!

    Great thread.

    i have been playing with this small aussi cadet rebarreled to 218 mashburn B and it is a nice shooting rifle tho a little heavy for a walking rifle.it will do 1/2-3/4 inch groups at 100yds from a rest and will push a 50gr bullet at over 3000fps. eastbank.
