Two years ago, I aquired a Kit of Castings plus Timber and Barrel for a 12 Gauge Greener type Martini GP Shot Gun. These where retailed by Brownells many years ago.This Kit had been with the previous owner a long time.Some parts where missing, ( Extractor and Cocking Pawl ) Which I made.Using an ex Swedish Rolling Block 8 MM Barrel, one turn in fourteen inches it is now a 32.40 Single Shot Rifle.The casting required Filing, polishing and case hardening. I used the kit Butstock and made a new Forend.I shortened the Barrel at the Breach end, made a Chamber Reamer.I ordered 32.40 Brass from Buffalo Arms (100 ), made a Bullet ( Boolit ) Mold. Had the Rifle Proofed at the Birmingham Gun Barrel Proof House.The Cases take 40 Grains of Fine Black Powder. The Bullet weighs 180 Grains. She shoots good and even ejects the cases with a fast pull of the underlever.Fitted a Tang Sight and a Tunnel Foresight.
Since then we can no longer purchase Cartridge Components from the USA due to recent U.S legislation.Good Job I stocked up on 45.70s and the 32.40s.They are obtainable here from Agents but at a massive mark up.
