After quite a bit of research and experimenting, I've settled on 14.7 grains of H-110 when using the X-treme plated bullets. With the Remington FMJ bullets, I use 15.0 grains of the H-110. For me, the starting load of 14.0 grains of H-110 would not cycle the action reliably and gave "sooty looking" cases. I use CCI #41 primers with both bullets and a mix of cases, but usually LC. This works for me - I am not responsible for any reloads other than my own. - Bob
Note: This is with the current formulation of H-110 or W296 - the older powders may have been slightly different.
