I don't know if any of you have tried Ramshot's True Blue powder, but I took the plunge and got a 4# bottle of it.
I loaded up a box of 45 Colt, using a 255gr commercially cast bullet... the data sheet suggested anywhere from 7 gr or so, all the way up to 13 or 14 gr... the "old" low pressure loads were around 7.5-8.8 gr, and the higher pressure "Ruger" type loads were 12.1-14.2... I don't really want a rompin-stompin T-Rex load, so I started at the low end of the Ruger loads.... 12.0gr.
Man, this stuff, to use the old worn out expression, meters like water... it's a very small grained spherical powder that just flows with no hangups. My Lyman 55 gave me less than a half-tenth variation....I threw/weighed the first 5, then the 5th one after that, then every 10th one. I got that variation on ONE of my thrown-then-weighed charges. That's almost a non-existent difference.
Now to see if it goes bang.... range report to follow...
