PLEASE NOTA BENE:: I IN fACT "Did Not" recommend Loading with Unique. If you could read my statements as well as you can "Pounce" upon them you would see that I stated there were no current pressure testated data available for it & listed it for "Historical Reference Only". You may well call that Anecdotal. It was however published data from a stated source, though stated to be obsolete & unrecommended.
On the other hand "Do You" have any data for 2400 in loads as light as 3/8oz in a velocity range suitable for a Black Powder era Gun either current or obsolete. I thought Not.
Also I note you have given him actual loading recommendations, I did not. Would you not consider those recommendations "Anecdotal".
The major factor in pressure, thus powder burn rates is load density, ie amount of weight to be moved per SqIn of bore area. A 1/8oz change of weight in a .410 is not an insignificant amount. As noted earlier this is eguivelent to a 3/8+ oz change in a 12ga. Would you take data for a 1½oz 12ga load & recommend simply dropping back to 1 1/8oz of shot & cutting the charge a little "Of the Same Powder" for someone desiring to shoot a short chambered Black Powder 12ga. I Thought Not.
Why in the world would you then recommend it for a .410??
