Hi Larry,

It's a huge advantage in the 25 and 625 revolvers in 45 ACP if your cast bullets can provide a press fit into the throats.
These revolvers don't have throats in the conventional sense.
Whereas you find a gentle conical transition from the chamber area forward to the throat (think 38 Special, etc), with the ACP it's a hard shoulder with no transition between chamber and throats. Of course, this is necessary for headspace purposes when using a rimless case. Unfortunately, often this sharp shoulder will shave off a bit of lead, which is not good for accuracy. Also, it builds up making continued shooting more difficult...chambers get gummed up, cartridges don't fully seat, and the cylinder becomes difficult to turn as the casehead rubs against the recoil shield.
A press fit cast bullet will get the bullet started and aligned with the throat, kind of like your Hämmerli free pistol when closing the breech presses the driving band of the 22 LR bullet into the throat of the barrel. This is a bit different than DWALT's concern about the cartridge itself being tight in the chamber.

Do any if your revolvers allow those HBWCs to be dropped or pressed through the cylinder throats?

Jim

PS: cool bullets! Wish I had the mold!
