Been reading up on loading for 308 subs and it would appear that 180 - 225 grain bullets coupled with Trail Boss powder are a good combo. Is Trail Boss one of the banned powders ? Just wondering if I need to seek a viable alternative .
Looking for recommendations 155 or 168 grain for the above along with COL .
Given that I need to have a regular supply of powder ,looking at using TAC or others that are available going forward
Thanks
