My best results so far have been Hornady XTP/HP 240gr with 23.3gr of H110. I have went as hot as 24gr of H110 (published suggested max), but accuracy seemed to fall off a bit. My favorite load for .44 mag is Hornady XTP/HP 200gr bullet with a charge of 26.9gr of H110. All of the above has been tested in MY gun. Every gun is different, always start with lower charges when changing brass, bullet, primer, etc.
