45acp and trailboss

[Ol` Joe]

Hodgdon lists loads for the ACP with Trail Boss on their web site. They show 750-850 fps depending on bullet. I don`t know how well your gun will track Hodgdons data but it is worth a try IMO.
One has to remember the smaller the case volume the higher pressures will be with same wgt loads and bullets. The huge 45 LC may need a full case of powder to reach 800 fps but the smaller ACP case may only need 1/2 that amount with the same wgt bullet.
