New 32acp Beretta 3032 w/ 2.4" bbl. came with printed warning not to use loads exceeding 130 ft/lbs.
goldenloki.com reports 32acp S&B 73 gr. JHP as 135 ft/lbs out of a Kel-Tec P-32 with 2.7" bbl.
Questions:
Is the reported 5 ft/lbs over the recommended max energy a significant enough difference that I should be concerned about damaging my Beretta?
Is muzzle energy purely derived from a formula of from actual tests of some kind?
Are muzzle energy calculations subject to a standard deviation?
Okay, you engineers/physicists, put your heads together and clear this up for me. Please. Thanks.
this is not rocket science, if you build up too much pressure in the breach it will stretch the guns tolerances out. If the gun is limited to a certainty bullet load/speed and you want big/better get a bigger gun. It has limits because for safety reasons. 5 ft per seconds in nothing but 100 ft or better I would wonder with a small cal. Like that
