looking for load data

Recommended Posts

As 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. 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 
load.
Start 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!

And yet, for cartridges that DO have load data for Trailboss, it is lower charges listed than if the formula had been used.  Strange.  I sent them a message via their website once asking about that for a particular listed load but got no reply.  It is a versatile powder for sure.
