...Hodgdon's instructions for Trail Boss are to mark a case with where the base of the bullet will be, fill the case to there, and weigh the powder. That is a safe maximum load. Multiply this weight by .7, and you have a safe minimum load. Since your case is "reasonably" full, you should not have the position sensitivity problem.
In my 30-30 it only takes 12 grains of Trail Boss to fill the case. A jar of TB is only 9 grains, and that is all that will fit in the jar...
That is useful info as I like to dink and plink around with my .30-30 and cast bullets. I don't see that on the Hodgdon website or the IMR website. Do you have a link to that information?
