I load for a 10" Max in a Contender, 180 Horn XTP/HP over a close-to-max load of 296, it does real well. At least on paper, haven't had the opportunity to try it on deer yet. I've also loaded 158 XTP/HP over 296 , accuracy is good....but most will tell ya to go with the heavier bullets in the Max. Guess they feel the XTP will explode rather than penetrate ?? I like it, light and easy to carry....and a real pleasure to shoot off the bench.
