Trail Boss Alternative for subs in 308 win family?
So since trail boss seems to be gone indefinitely, would there be a viable alternative that would be safe for subsonic loads in a 308 Winchester sized case?
The specific cartridge I'm working with is 7mm-08 and I'm hoping to push either a 150gr hpbt or a 175gr round nose at around 1050 fps. Both bullets are close to the same length. My rifle has a 8.5" twist so these should be stable according to Berger calculator.
So my only hold up is if I can actually find a powder other than trail boss that will work safely. Thanks in advance!
