Yeah, some people try to load .44 special loads in .44 magnum cases, and put a light charge of a fast-burning powder in a big case. They don't realize that the extra air in the case can cause the light charge to detonate, with all of it burning simultaneously, generating extreme high pressure. But they learn, sometimes the hard way.

I always believed they were EXACTLY the same. Winchester sold bulk 296 to Hodgdon who packaged it as H-110.

I'm slower than the 7-year itch, but it keeps accidents like this from happening.

H110 for the .357 Magnum as well.

I don't find it necessary to weigh charges of H110. I throw them right out of the measure. I double check the measure by weighing every 100th charge. Neither my redding measure, nor my Dillons have ever lost calibration.

I am not into reloading but double charge means you put double the powder load in the case when reloading? How do manufacturers make sure they don't double charge? This seems very dangerous.

Sometimes the commercial/factory ammo companies do screw up. I had a box of .45 Colt "cowboy action" ammo (50 rounds) a bout a week ago that had 2 squib loads in it. I don't remember the brand, and don't have it here at work, but it was a popular brand. It's been several years ago, but I remember one box had 7 squib loads. What a pain it was pounding the bullets back into the cylinder chamber so I could unload the crap.

The only powders I will use for .44 mag anymore are 269, H110 or Accrate Arms #9
Same here Viking. I like the slower burning powders also. H110 and 296 are great powders.

I guess anything is possible but the way I load 44 mag if you double load, powder is gonna be running over the side of the case. I guess if you were doing lite loads it could happen. One of the reasons I like my single stage press, do one process at a time and use the next step as an inspection process for the step that was just performed.

I've been thinking about H-110 vs W296, and I think that maybe the reason Hogdon still cranks out W296 is that a lot of reloading manuals specify W296, so in order to not lose the customers that use those manuals, they crank the powder out under both designations.

That makes sense.

And BTW, if you feel the need for "light" loads in your ,44 Magnum, why not get a box of .44 special brass and load .44 Special loads?

I saw a Super Black Hawk that was blown up. The shooter had a badly wounded face and hand. The idiot heard that 23 grs. of 296 was a good load. He did not have 296 but reasoned that 23 grs of Blue Dot would work just as well.
