Dealing with an elbow injury has had me playing with glocks for awhile, the 9mm is a little easier on me.

But I miss my 41 magnum something fierce. I broke it out today and ran a few cylinders of 41 special through it and that got me thinking...

Lets say I want to load up a mouse fart... lets say 5.0 grains unique with a 215 grain ball, which should go somewhere around 750ish fps maybe.

If I kept the same charge of 5.0, and loaded a 265gr ball which will now be going slower.... would that recoil more because of the heavier ball or less because its going slower?

Energy is equal to mass x acceleration^2, so it would seem that if we have an equal and opposite reaction, and velocity is squared when bullet weight is not, that speed would be the greater portion of the recoil equation.

This is more of a thought experiment because I don't have any heavy ball on hand. *Edit* I just picked a random powder charge weight out of the air, I'm not saying I am committed to loading 5.0 grns of Unique.
