What is the formula for computing foot pounds of energy at the muzzle?
A. Velocity x Velocity x bullet weight divided by 450436 equals energy in pound-feet (Velocity is in feet per second, bullet weight is in grains) Example: 180 gr bullet traveling in my 10 mm @ 1200 feet per second: 1200 x 1200 x 180 = 259,200,000, then 259,200,000 divided by 450436 = 575.4425 lbs-ft.. 054X122099 RELOADING RELOADING USED BRASS Q. Is this true? Brass fired from a Glock is virtually useless to reloaders because the chamber of a Glock is unsupported which causes the brass to bulge?

Nary a problem. I don’t use Dillon dies, I use RCBS with LEE crimp dies. A. #3 I’ve reloaded tens of thousands of Glock-fired cases, many
