CAUTION: The following post includes loading data beyond currently published maximums for this cartridge. USE AT YOUR OWN RISK. Neither the writer, The High Road, nor the staff of THR assume any liability for any damage or injury resulting from use of this information. That being said...
My objective has been to develop or discover a handloaded .45 ACP cartridge using a 225 grain lead bullet to 900 fps or more, if possible. I'm not concerned so much with pistol longevity as I am with maximizing the power potential. (Rational: $500 pistol / 10,000 rounds = $.05 per round.) I don't have a chronograph or pressure testing device, so I'm dependent on your testimony for guidance.
Here's where I'm at: I'm using a Ruger P345 loaded with Hunter hard cast 225 truncated cone bullets and 6.6 grains of Unique and CCI 300 primers. The fired primers look just fine, the P345 functions just fine (with a Wolff 17 lb recoil spring), the cases are totally reusable, and I can't detect any leading after 400 rounds of this stuff. From what I read and from observing the dust thrown up behind the targets, I'm already beyond the 830 fps standard for 230 grain hardball round, and maybe above 900 fps. This is will be good enough, if I'm within safe limits.
My question is, if I can't tell that I'm over pressure by checking the fired cases and the way the gun behaves, what else should I look for?
