Petander: We are basically improving on the versatility of the Brown Bess Musket (1720-1840) by inventing more stuff to shoot from our guns.
Our Guns don't foul due to Smokeless Powder, our Guns are more accurate due to better machining and closer tolerances. Most of our guns are Repeaters, and some even have Rifled Barrels.
Funny thing,,, That slug you show above would probably shoot real well from a .75 cal. Brown Bess Musket in fact I bet it would be very similar to shooting it from any Smoothbore Shotgun we have now. Just more smoke. (Maybe one wrap of paper to take up the slack.)
So it would appear that what we are doing here would be transferable back in time to earlier uses. I wonder if people from 200 years ago would find these new projectiles useful or if they would just as soon shoot round balls?
Questions flooding into the mind of the concerned shooter today. Am I more Lethal now than 200 years ago?
Probably not! They all carried Guns, Big Knives and Tomahawks and actually knew how to use them.
The average English Archer could get 10 Aimed Shots off in a minute and was good out to 80-100 yards. Muskets not even close.
We've known how to kill things for a long time. Are we better at it now? Not by as much as you would think.
