The bullets I'm using are also plated so I'll not worry too much about excessive pressure. Alliant's loading chart agrees with Speer. Thanks for the reply, Nick

I have a new Kimber stainless target II LS and am reloading 10mm for it. I am a little confused about loads from different references. I loaded up a box using my Speer reloading manual 13 which listed 8.0 grns of Unique under a 180 grn bullet. Now I notice in my Sierra manual the the max load for Unique under 180 grn bullets is 6.3 grns. Why is there such a difference? Should I be concerned about shooting these rounds in my new Kimber?
