I am a regular open class USPSA shooter. We shoot .38 Super and some related variants loaded to a power factor (bullet weight in grains x velocity in fps/1000) of 165, down from 185 a few years ago, but still hotter than factory .38 Super, so all of our ammunition is hand loaded. People are for ever handing me loaded rounds dropped by other competitors while unloading and showing clear at the end of a stage. I smile and say thanks, then put them in in the squib box. I am not going to blow up a $3500 gun to save a quarter.

Those super-duper .38 Super loads are one reason I don't shoot anybody alse's reloads. I have a Series 70 .38 Super in near-NIB condition, and I love to run a box of factory ammo through it once in a blue moon. The .38 Super was the preferred caliber of the Dillinger gang, on the theory it would penetrate the body armor of the '30's.
