Ok, it has been many months since anything has been added to this string..
It has been belabored by us, as to the dangers of under-loading and pressure wave events, i.e., Detonation..
So there I am on AmmoGuide.com, looking at data tonight and see this at the bottom of the page.. (http://ammoguide.com/cgi-bin/ai.cgi?sn= ... &catid=628
)* H110 and W296 CHARGE REDUCTION WARNING
H110/W296 Loads should not be reduced more than 3%.
Reduce H110/W296 Loads 3% and work up from there. If reduced too much, H110/W296 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.
DO NOT REDUCE H110 or W296 LOADS BY MORE THAN 3%.
Now, the 3% thing is a pretty severe tolerance, in my opinion, and have stated that 20% reductions have been well documented in the literature, but that I personally do not like more than a 10% reduction, here's a recommendation of not more than 3%.
Does lil-gun fall into this category or other powders? Me thinks tis-be-so, Matey. Although, some powders are more prone to a Pressure Wave Event, none are totally excluded.
You've been warned, now go make us proud..t
