Testing some Third Model Dragoon loadings.
Boolits are of course being cast from soft lead.
Sizing diameter is 0.450" due to the chambers being 0.451" (and 1.47" deep).

Firm seating of the boolits on the powder charges provides metal to metal sealing.
These charges of FFg are close to taking up all the available volume within the chambers that's left over from the lengths of the boolits, the boolits' noses being a little below the front plane of the cylinder.
#452389 (195 gr.), 40 grains FFg, 762FPS.
#454613 (plain base adjusted to 230 Gr.), 35 grains FFg, 709FPS.
Ideal #45266 is a bevel base design that I've found to work well in the Walkers and Dragoons. That bevel base makes for nice loading and the nose generally fits the loading rams. Never bothered to chrono it but maybe this time.
:rolleyes:
