Today I acquired this H&R .410-12MMChoke Folding Single Shot in excellent condition. The serial number is 28xx. It seems to be in excellent original condition. I spotted it on the shelf of a LGS/Shooting Range at a very attractive price and was even able to get a small discount.
I believe it’s markings indicate that it is full choke. I think it is for 2 1/2” shells, but I am not sure. It has beautiful color case hardening and a perfect mirror bore.
I am interested in getting a rifle barrel fabricated for it in .32 S&W Long or .32 H&R Magnum, and I have sent an email to John Taylor inquiring about this.
I would love to see some fabricated rifle barrels that have been made for your single shot .410’s.
