Thanks for the input mal!!
I went back and and looked in the Speer reloading manual at the 125gr lead round nose. I thought there was a power pistol loading there but it was winchester action pistol. Perhaps the 122gr is too light to cause effective combustion of the slower burning powder?
In any event in today's litiginous society I can understand your reluctance to post reloading guidance. I appreciate your thoughts on the subject. I guess if I want higher load density I go to unique.
Could you please post the URL for the Alliant web page? I'd like to book mark that one.
Check for that double charge<g>
