seems the 44 mag reloads I shoot are about 900 ft lbs. That's about the limit I want to shoot in a handgun that weighs 2 1/2 lbs or less.

I have some issues with this table!!

I really think the .45 ACP loses more then 80 fps from muzzle to 100yrds.

I also think the .357 is a bit slower at 100yrds then 1015 fps

Other then muzzle energy they all are suspect (no BC factors)

My .02$

Disregard last post.

Not enough coffee

Handgun data is in feet not yards

still wondering why no BC info

A 180 gr RN .30cal fired in a .308 will not perform the same at 100 yards as a 180 gr Boat Tail Spire point, in this chart there is no way to enter this.

Hummmm
