Okay - I realize this post is nearly a year old, but here's some loads I had worked up using a 300gr. XTP in a 10" Contender:

All loads use WLP primers, and bullets seated to 1.600".

10.5 Blue Dot = 976 fps.
11.0 Blue Dot = 1005 fps.
11.5 Blue Dot = 1059 fps.
16.5 H110 = 1070 fps.
17.0 H110 = 1102 fps.
