Newbie needs 45acp info for green or blue dot

[Toscano]

Newbie, both to the .45 ACP world and reloading for the .45. My question arises for my initial loading for my Taurus PT1911. As a side note, it fires commercial 230gr ammo just fine. I have, from a previous handloader, 1# each of Blue Dot and Green Dot and was wondering how compatible they are to .45ACP loading. I've been given differing information and need some decent clarification. I'll be loading 185 and 230gr RN FMJ. My background is mainly in rifle reloading and am not used to these small grain weights vs cartridge fill...also, is taper crimping suggested, or mandatory? I would appreciate as much information as possible. TIA.

Lyman data:
185 Jacketed SWC Blue Dot 7.3 = 666 10.2 = 1015
230 TMJ Blue Dot 8.3 = 684 9.2 = 806

I don't have any data for Green Dot.

A taper crimp is REQUIRED. The .45 head spaces on the case mouth so too much crimp can be a problem. Too little crimp could result in a KABOOM. The crimp MUST prevent the slug from being pressed further into the case. As you know, smaller case capacity generates higher pressure.

Neither powder would be my first choice for the .45 I like Power Pistol, W231, and Titegroup.

Happy shooting

PS: I recommend you seat and crimp in separate steps.
