Thank you H2OBUG! My Ruger Bisley Blackhawk is (new), so I should be ok.

I usually work up all of my loads, but I have a 10 month old son who likes to use up most of my free time, which I gladly ablidge!

Trying your "most accurate" load may very well save me a bunch of time!

I have 6 rounds loaded and waiting with a CCI-350 primer, 250 gn Hornady XTP, and 20.5 gn of 2400 powder. I just need to get out and shoot a target and check my group! Thanks again for the help.

I have never heard anything about noy using the Magnum primers and Aliant powders ... I thought that the magnum primers should give a more consistant burn rate.
