I contacted Tom at Accurate Molds and asked that he design a light weight .45 cal bullet to use in a cap n ball pistol that the OAL would be roughly that of a ball. This idea cap about after having read someone using a .45 Colt 155-160 grn bullet. The idea that it was roughly the same length, which wouldn't take up any powder capacity, yet have more bearing surface should/would (don't recall if it was theory or observed) increase pressure and velocity.
What he came out with was a 180 grn (WW) bullet .460" OAL.

He also designed a lighter bullet and came up with a 160 grn variant.

Next will be a heavier bullet ~250 grns in weight with a slightly wider meplat.
I've also asked him to design a light weight bullet for the .36 cal pistols.
What are your thoughts on the 160 and 180 grn bullets working in both the slow twist and faster twist barrels of cap n ball guns? Is there any reason to believe it won't be stable?
