Another 45 COLT question...?

Personally, I wouldn't use Unique for your wadcutter load. I load a 250gr wadcutter for my .45 Colt, and I use 4.0-4.5gr of Bullseye. When loading to a low velocity, you want a powder that will produce your desired velocity at a pressure level that is at or near what it is designed to burn at. Just MHO.

235 gr wadcutter bullet seated almost flush with case mouth. 7.2 gr of unique, cci lp primer. The Q: is this about a 750 fps load?
I would think it should be more like 710 from a 5.5-6" and 750-760 from a 7-7.25". Only the chronograph will tell though! They're cheap these days but invaluable as a loading tool.
 
"...7.2 gr of Unique..." That's below minimum(8.1) for a jacketed 230 grain(close enough) bullet according to Alliant. Where'd that data come from? Your WC cast or jacketed? What's the barrel length?
You really should be loading for accuracy not velocity too.

Sunray,

First, it's a lead bullet, and lead bullet loads are typically loaded lighter than jacketed bullets to reach the same velocity. But more importantly, wadcutter bullets are loaded nearly flush with the case mouth, meaning more bullet is enclosed within the case and thereby reducing case capacity dramatically. It's an apples and oranges thing when trying to compare jacketed SWC/RN loads with lead wadcutter loads.
