Trying to get my head around "Trail Boss" powder here.
Say some ADI .308 reloading data for example.
150gr bullet + 47gr 2208 powder = 2937fps muzzle velocity. This is a compressed load for the .308
150gr bullet + 14gr Trail Boss = 1417fps muzzle velocity. Less than 1/3 of the powder charge and a lot less bang. So is the case 3/4 empty in this load?
I understood low case density was decidedly bad, and this would be real low...
What's the story?
