Re: .357 Powder
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Clark</div><div class="ubbcode-body">If one does reduced load experiments in 357mag, 44mag, 45Colt, etc with H110/W296, yes heavy bullets and magnum primers help, but to get down to 1/2 powder charge and have the load work, the roll crimp is the 600 pound gorilla.
And when the primer goes off, but the H110 does not, a revolver often jams with a bullet pushed into the forcing cone. It is really jammed bad until a ramrod knocks the bullet back into the cylinder. </div></div>
vinconco has it right - H110/W296 should only be used in heavy loads, and in that capacity, it excels (my #1). Hodgdon has a warning on their website to not reduce H110 loads more than 10% below max, or bad things can happen. There are much better powders for reduced loads.
(EDITED TO ADD
Correction - their number is 3%:
<div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body">For those loads listed where a starting load is not shown, start 10% below the suggested maximum load and then approach maximums carefully, watching for any sign of pressure (difficult extraction, cratered and flattened or blown primers, and unusual recoil). H110 and Winchester 296 loads should not be reduced more than 3%.
Reduce H110 and Winchester 296 loads 3% and work up from there. H110 and Winchester 296 if reduced too much will cause inconsistent ignition. In some cases it will lodge a bullet in the barrel, causing a hazardous situation (Barrel Obstruction). This may cause severe personal injury or death to users or bystanders. DO NOT REDUCE H110 LOADS BY MORE THAN 3%. </div></div>
