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%. "
