I picked up a 44mag Bisley Hunter about 2 months ago and Love it! I have had it out at the range every weekend developing loads. If you reload, you may find this useful.

Here is the most accurate load I have found to date will put all 6 cylinders in 1" from a seated bench rest at 25 yards repeatedly.

String: 2
Date: 08/09/10
Time: 05:01:05 PM
Grains: 240
Hi Vel: 1522
Low Vel: 1473
Ave Vel: 1493
Ext Spread: 49
Std Dev: 16
24.0gr H110 Fed #155M COL 1.580" Trim 1.255"
Velocity Power Factor Ft/Lbs
1491 357.84 1184.59
1486 356.64 1176.66
1503 360.72 1203.74
1473 353.52 1156.16
1522 365.28 1234.36
1488 357.12 1179.83



Just for comparison here is data from the Hornady Factory 240gr XTP, also very tight group but not as good as the load listed above.

String: 2
Date: 08/06/10

Hi Vel: 1508

Hornady Factory 240gr XTP

1476 354.24 1160.88
1471 353.04 1153.02
1508 361.92 1211.76
1484 356.16 1173.49
1481 355.44 1168.75
1484 356.16 1173.49

I run loads up and down all the way to 25.2gr and played with mag and non mag primers (very little difference regardless of charge). 24.0gr of H110 was constantly far more accurate than any other load. Even bumping up to 24.5gr would almost double the grouping to 2" at 25 yards. The group would tighten back up some at 25.0gr but for the slight increase in velocity it just wasn't worth it. Of course this was in my gun with my hands in 85-90deg temps at 1500' elevation. But it may be a good starting point.
