![]() ![]() One can find his load somewhere in that range. We maintain excellent results from 100% loading density, down to 70 % loading density. Compression affects the ignition of this powder, causing less uniform velocities and lesser accuracy. #240 grain 308 subsonic loads fullWhen one loads a full case with this powder, he needs to refrain from any compression. In normal cartridge loading, full cases generally provide the most uniformity and accuracy. By giving the powder such a “fluffy” measure, it utilizes most of the capacity of almost any case chosen. Few powders come anywhere near the 325 g/L bulk density of Trail Boss. “ Trail Boss is different from other powders due to its amazing, low bulk density. I reached out directly to Hodgdon with a few questions about the powder itself and this is what I found out. Start with this beginning load and work up to your maximum charge, all the while searching for the most accurate reduced 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. Then fill the case to that mark with Trail Boss, pour into the scale pan and weigh. ![]() 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. 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. Listed below we show a few examples of such loads throughout the Reloading Data Center, but the fun doesn’t stop there. These reduced loads make firing such cartridges as the 300 Winchester Magnum or even the 458 Winchester Magnum pure fun! However, Trail Boss offers superb versatility in rifle cartridges producing reduced loads using lead or jacketed bullets. “ Trail Boss was designed primarily for reduced loads using lead bullets in pistol cartridges. and its authors, do not assume any responsibility, directly or indirectly for the safety of the readers attempting to follow any instructions or perform any of the tasks shown, or the use or misuse of any information contained herein, on this website. #240 grain 308 subsonic loads manualsConsult appropriate load manuals prior to developing your own handloads. They are only safe in the rifle shown and may not be safe in yours. WARNING: The loads shown are for informational purposes only. With the 308 Winchester paired with the 150 Pro-Hunter and 168 SMK, I was able to make loads that had a muzzle velocity of approximately 60% of the full power charge (1,933 feet/second for the 150 and 1,856 feet/second for the 168), but it is possible to go even slower and lighter safely, with another powder, Trail Boss. Most of my reduced-recoil load work to date has been with H4895, which is, according to Hodgdon, the slowest powder they have that you can safely reduce loads with. If you like your reloads fast and loud, I apologize in advance, this post isn’t for you. Even better, some of the loads have proven to be surprisingly accurate. No longer trying to get the most speed out of a cartridge, I’ve come to appreciate the light impulse of reduced rounds. This is a big change from my earlier (and younger) days of reloading. ![]()
