Nope Braindg.
The 2 bore is only ever fired with what are effectively "squib loads" with velocities on about 600 FPS. Reason?
At 600 FPS the owner was pushed back over 4 feet and he weighed 420 pounds.
the gun can take a real charge of powder and give 1500 FPS but the recoil would be so heavy that no one could use it.
It was commissioned by the owner so he could have bragging rights, nothing more. He was not even a hunter.
But the idea that it won't go through a 6" timber is WAY off base.
In fact at only 600 FPS it went through a 35 gallon trash can full of gravel.
I made a 4 bore that we did shoot 1500 FPS loads from. It went through 5 feet of green cottonwood. And it would be 1/4 as powerful as the 2 bore if velocities were the same.
Remember that the swivel guns on the bows of of gunboats in the War of 1812 were about 2 bore and they would sink other ships. Other ships made of heavy Oak. The barrel of my rifle is fully capable of holding the same charge and ball. I know, I tested it with that amount. At 1550 FPS the ball generated over 18,500 Foot pounds of energy.
And yes it was bespoke.
To the best of my knowledge I am the first man in history that ever made a sporting 2 bore. My old student Colin Stolzer has made several since, but according to the records we have been able to find, no one ever did a true 2 bore as a sporting rifle until I did this one.
This doesn't mean I am for sure and certain the 1st one to do it. It just means we could not find any record of anyone doing it before me, and no examples are known to exist anywhere before my gun was made of a SPORTING rifle made in 2 bore.
