HDY SP140 GR. SFT SPStarting Loads30,600 PSI39,100 CUPAs noted in the powder description section, TRAIL boss was designed primarily for REDUCED LOADS using lead bullets in PISTOL cartridges. However, TRAIL boss offers superb versatility in RIFLE cartridges producing REDUCED LOADS using lead or jacketed bullets. These REDUCED LOADS make firing such cartridges as the 300 winchester magnum or even the 458 winchester magnum pure fun!Listed below we show a few examples of such LOADS throughout the Reloading Data Center, but the fun doesn't stop there.
3 If you don't see TRAIL boss data for your favorite cartridge we have a formula for developing LOADS for all cartridges and it's simple to follow. This formula may be used in both RIFLE and PISTOL applications:Find where the base of the bullet to be loaded is located in the case and make a mark on the outside of the case at this location. Then fill the case to that mark with TRAIL boss , pour into the scale pan and weigh. This is your maximum load. Pressures will be below the maximum allowed for this cartridge and perfectly safe to use!Take 70% of this powder charge weight (multiply the maximum load from step 1 by .7), and that is your starting with this beginning load and work up to your maximum charge, all the while searching for the most accurate REDUCED load. Once found, the fun begins!27,100 PSI43,300 CUP29,900 CUP31,000 PSI27,100 PSI26,400 PSI31,600 PSI28,600 PSI Hodgdon Powder Company 350 GR.
