Why stop there? How fast would a 1 gr "bullet" go? :biglaugh:
Sectional density and momentum dictate how fast/light you can go. 185 to 230 grs is the useful range from a handgun - 230 being best if you expect barriers and/or heavy clothing.
We're not shooting at balloons.

Still, it is an interesting exercise in why Wildcatters are who they are. 11's mention of sectional density is key in that case (that's why Sig and others thought the little .357 SIG such a cool deal.) You take a garbage can size case and neck it down to shoot a bb and voila! Rilly fast bullet!!

 

I had chrono'd this load:

200gr XTP bullet
6.3gr N320
C.O.A.L 1.245

10 shot average was 1050fps....highest was 1157fps.

 

hmmm....



That highest velocity is a pretty far way from your average; I might be thinking about a different, more appropriate powder choice.....

 

Hey Honda01

Does the 6.3gr of N320 shoot clean or dirty?

If a 'bullet' will not penetrate drywall, I'd expect similar performance (or lack thereof) on a sternum or rib...or jacket.

45acp 230gram is still the king of defence hand gun ammo after 90 years we still look for ways to make it better but always come up short .

You mean like JHP's that open up to twice original diameter and have 12"+ of penetration?:biglaugh:

 

A loaded mag would weigh a bit too, It would be a dangerous load if you dropped on your foot though.
