Well it is the monsoon season here in the interior of Alaska and I have been able to get out to shoot only between squalls this summer.
I have been feverishly working up loads for a group of guns, usually able to shoot three or four guns at each chronographing session. Today was, among others, 44 special day and these are 3" S&W's one of stainless and one lovely little 24 blued gun, all original S&W. The stainless version of it the 624 is a little more used and and with a very nice set of African black wood grips.
Some of the loads I tried, quite honestly were rather pitiful, trying new powders in this case to launch the 250 grain WFN, plain base bullet. Hoping for only 850 fps and falling quite short making only about 750 and lots of unburned powder....back to the drawing board.
After about 40 rounds through this newly acquired 624, it began to lock up and and be hard to open. So common and so typical of this revolver after a few hard rounds but this time it was just light and moderate loads. But as predictable as ever I found the screw holding the cylinder latch loose. The second most common ailment I suppose is the ejectors threaded rod loose. It was tight and of course this one is left hand threads which helps keep it together.
This is a nice gun and I think I can make it do what I want but 3" just isn't much barrel to get a bullet going very fast. I thought I could use mid burning rate powders and get things to happen but not so far. The best load in this barrel length has been 9.6 grains of Blue Dot with this 250 grain WFN. That one will let you know you have hold of a 44. It gave me the 850 fps I wanted. It is funny with these too light loads of N105 the heavier bullets were progressively faster than the lighter because the ignition was better. Also I think Federal 150 primers are not any help with this powder. I'll find some CCI-300 and try again. I think 12.0 grains will get the needed velocity. No body publishes loads of this type for a 44 special. Once again out on a limb....what I do best, I guess.
