I joined Loaddata.com. These are the Wolf Publishing people that produce, Rifle, Handloader, and Hunter magazines. It has all the manual data, Pet Loads, and Handloader mag data. Brian Pearce has a recent article on the 45LC, using a 5.5 inch Bisley as the platform. He has categorized the loads as 14,000, 20,000, and 32,000 PSI. I use a 275 LBT and my current recoil threshold is at the 1100fps, 20,000 PSI level.
