There is nothing narrow about the operating range of a slow burning powder that is designed to produce maximum obtainable velocity.
1100 fps isn't even plinking velocity for a 44 mag. and isn't nearly the power house needed to hunt deer or any other big game animal with confidnce. Using H110 or it's twin brother 296, will get you close to 1900 fps without excessive pressures to get there. Out of a 8" barrel I've been sucessful in getting well over 1900 fps with a 225 gr. jacketed bullet, and without any excessive pressure signs. Don't get me wrong, a load of this type will let you know you've dropped the hammer, oh ya! In my experience, those who have had questionable results with either of those powders have reduced the charge to below the published minimum data, and, or, have tried to use it with a standard primer rather than a magnum primer. Either of those methods will only deliver disappointment and unpredictable results. Once you get the charge up where it needs to be and as indicated, the pressures and other pertinent performance elements stabilize and produce excellent consistency, with both velocity and accuracy.
I'm not bashing 2400, it's another excellent powder, but doesn't deliver the performance potential for a magnum cartridge. For full house magnum performance which, was what that the 44 mag. was built for, nothing does it better than H110 or 296. Some get close but simply can't deliver all of it.
