I use 6.3 gr of Unique, CCI 300 LP Primers and a 250 gr RNFP for 45 Colt loads in my Uberti Cattleman (SAA clone). I have had good accuracy with it and it has been consistent. Alliant Powder lists the load as 6.0 - 7.5 max (I believe, confirm it on their website) for the 250gr 45 Colt. I settled on 6.3 as I am using a LeePro 1000 and the powder disc is a little limited in fine tuning. Using the .76 size disc gives me 6.3 grains. The next size, .82, is right up around the max. That beats up a SAA clone a little too much for my comfort.

One word of advice, WATCH FOR DOUBLE CHARGES. That is a big case you are loading and the smokeless powders are much more efficient. If you double charge you may not overflow the case, so you really need to keep both eyes on the job.
