I have no issues with getting 72 gr of Goex 2F into my cases. I seat 540 grain Paul Jones Creedmores to the first band (right around .650) plus an .060 LDPE wad, so that is right around .710 deep from the case mouth.
It is crammed in there pretty tight.
For me, this has been the best way to get Goex to shoot accurately, ie: compress a lot of powder in. I do the same with the other 45's I shoot. 85 gr of 2F in the 45-90, 98 gr of 1F in the 45-100 and 107/8 gr of 1F in each of the 110's.
