What lot numbers?
Standard deviation would be more helpful than ES.
Good work.

Re: Old Eynsford verses Swiss

Re: Old Eynsford verses Swiss
Was there any compression in these loads?
Was there any next tension also?

Re: Old Eynsford verses Swiss
There is only one reason why the FFg grade of Olde E is faster than Swiss ... The grain ratio mix, 4.27% of 40 mesh in a FFg grade and a tad of 50 mesh to boot? Give me a 'cheating' break!
Swiss FFg (250.504)
20 mesh - 76.16% retained
30 mesh - 23.50% retained
Through - 0.34%
Olde E FFg:
20 mesh - 62.81% Hold
30 mesh - 32.32% Hold
40 mesh - 04.27% Hold
50 mesh - 00.60% Hold
60 mesh - Trace

Re: Old Eynsford verses Swiss
BTW, there is an Industry Standard for all grades of blackpowder and all grades Olde E are outside the Standard

Re: Old Eynsford verses Swiss
Would be nice if everyone would abide by industry standards,
but, if Olde E can work better for shooters outside of the standards,
so be it.
