I'm beginning to read more about TrailBoss being used in reduced loads in bottle neck cases.
I loaded 12.3 grs. of TrailBoss behind a SAECO # 315 HP, sized .310" and primed with a Wolf LR Primer.
I seated the nose of the bullet lightly into the lands.
I was amazed at the group. A very accurate load.
I came back to the loading bench and loaded more !
Out of curiosity, I willfully tried to throw 24.6 grs. ( a double charge of the load that had shot so accurately ) of Trail boss into a 30 / 06 case, just to see if it was possible to throw 2 charges of 12.3 grs. into a 30 - 06 case ( A Double Charge ) IT CAN'T BE DONE ! !
24.6 grs. overfills the case and powder spills out onto your bench.
So, If you'd like to shoot an accurate reduced load in an 06' without the fear of a " double charge ", TrailBoss is a good place to start looking.
