Sir Chad carries a twelve pounder hand cannon, and when he ignites the powder the ball sails true into the main deck of the pirate, but the recoil capsizes his vessel.

The Energy of the .45-70 is 3867 J. For comparison: 9 × 19 mm NATO, used in guns, has 481 J, 5.56 × 45 mm NATO and 7.62 × 51 mm NATO, both used in rifles, have 1800 J and ~ 3600 J, respectively.

So, a derringer is a small pistol, usually with two shots, made for close-range self-defense. Normally they use, well, pistol rounds, like a 9mm, which has like, 700 joules of energy or someshit like that. When you fire a lightweight gun, you definitely get some kickback from it, even with a pistol round.

A 45-70 is a big-ass rifle round with something like 4000 joules of energy behind it. You uh, you put that in a little derringer and pull the trigger, both you and your target are gonna feel it.

This also might help put it into perspective

A very energetic rifle round (where the mass of the rifle helps control the powerful recoil) being fired from a very low mass handgun would feel quite a bit like holding onto an exploding grenade.
