To be clear, I'm not a 'purist'...don't have expensive custom guns that are supposed to be "period specific" and all that...but I do use TC Hawken Flintlocks, realBP, black English flints, and patched round balls...hunting has never in my life been as rewarding as it has beenfor the past four years...first Flintlock squirrel was about as big a deal as the first Flintlock buck!

its hard to think that a VOLUME measure would be so close to being precise compared to powder scale on geox 2f.that was a SURPRISE too me.its hardto think that you pour in your powder in a MEASURE ,dump it in a scale pan, weight it and it is almost within tenths of gr.close to powder measure reading .that was a surprise to me, for sure.i expected to see like maybe 2 ,3 4 gr. diffference in my POWDER SCALE reading compared to powder measure.that never happened.

I understand this.. I was just surprised at how when I measured a volume weight of 100 grains ofTriple Se7en 2f, it weighed out at average, 68 grains. I would have guessed it would have been a little more then that. I just find it interesting.

cayugad, now that is interesting too, i learned something there.

Well due to a different post, I went and read the instructions again on the scale and found out there is a "g" for grams I am guessing, and then there is a grains setting. I was not using the right setting I think.

Here is data on weighed charges

interesting reading...thanks for the post.

Cayugad, your scale was on the right setting. 1 gram = 15.5 grains so if the scale was on grams you would have got a reading of like 5-6g's when you put 70-90 grains on there. You would havenoticed a problem right away.

I think the data tables are reversed for FFFg vs FFg at this web site:

http://www.hpmuzzleloading.com/LoadsBallistics2.html

All my APP type powder FFFg wieghs Heavier than FFg.

I also tap my powder measure till it won't hold any more. My findings are:

Trip7 FFg
.80 x grains by volume = Trip7 FFg Actual Wieght

.80 x 80gbv = 64gaw
.80 x 100gbv = 80gaw
.80 x 120gbv = 96gaw



APP/Gold/Pinnacle FFFg
.92 x GBV = FFFg Actual Wieght

.92 x 80gbv = 73.6gaw
.92 x 100gbv = 92gaw
.92 x 120gbv = 110.4gaw

i noticed under NOTE .it said that uncle mikes brass weighted a black powder 3f volume charge of 100 grs and it weighted 99.3 on the powder scale.i used my 35 year old THOMPSON/CENTER BRASS volume measure that goes from 50/120 grs. it was only .5 to 6 of a TENTH of a grain off from the volume measure.example, my 100 gr measured in the brass thompson was 100.5 in the powder scale. if i TAPPED the measure it was 101 gr with 2f.i was surprised it was not like 2 ,3.4 GRAINS diffferent than the powder measure. there is no reason to weight a charge ofGEOX 2F BLACKPOWDER USING THE THOMPSON BRASS VOLUME MEASURE.good articile, i learned.
