44 special loads with H110 powder?

[Lost Sheep]

(edited for brevity)
But the more important point that some people have mentioned in this thread is that the OP exhibits a marked lack of knowledge and understanding of the reloading fundamentals, and for those reasons, I absolutely agree that he should NOT be trying to use this powder in .44 Spl. He has been given good advice on better choices.

I re-read the thread and see that while the OP exhibits a lack of knowledge, he does exhibit laudable judgment (he came to ask for advice and is taking it. See his posts 33 and 38.

Few of us came to reloading with understanding of reloading fundamentals, either the mechanical aspects or chemical ones, much less internal ballistics.

These, (as well as any other [safe] .44 SPL. load) are safe to shoot in any .44 mag chamber. When you reduce the charge of H110/WW296 powder from these loads, you ask for trouble in the form of extremely high (read that UNSAFE) pressures.

This is a common misconception...

The issue with downloading H110 is that it is hard to ignite, and can easily squib if pressures are not high enough to complete the burn...It has nothing whatsoever to do with 'detonation', or Secondary Explosive Effect (SEE)...

Hodgdon's own warning on the old reloading data front page stated:

" 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%. "

I was experimenting with 110 in 38 spl loads which were also published data in my older Speer #9 manual. They seemed to shoot fine from my GP100, so I tried them in my 38 snub which also seemed to shoot fine. Then I put them through the Chroney and found 5 round groups varied in velocity by 250fps from 5252-775!

When I went above published data for 38, they got a LOT more consistant, and group tightened up (in the GP100), BUT I did not even consider shooting them in my 38 at that point because I believed them to possibly be above 38 spl standards, and had no way to test pressure.

Interesting experiment for an experienced loader, but I would never send a newbie down that road!
