Really interesting reading !
I am thinking of rifle calibers mostly, not cannons and arbalests

What was the dimensions / caliber on Pauly's rifle ?
Nice that the 360 2 & 1/4 is a really early cartridge. A number 1 favourite of mine to shoot. Perfect.
Were there more "in the middle" calibers coming in the early years, not down to 22 short and not up to 577 ?
