That is if you remember to put any powder down the bore at all - right?
Ain't nothing like that feeling of pushing your PRB or conical down the bore and watching your indicator line on you ramrod disappear past the muzzle. One of those "Awww Crap" moments.

The rifle is rated to 110 grains of powder, so I was still in the limit of the rifle at 105 grains. But what surprised me is, normally I shoot 90 grains (according to my notes) and never pushed the rifle harder. Now 15 grains is not that much more, but it seems this rifle is a powder pig. That would have had that roundball really screaming down range.
90 grains shows 1950 fps and 1478 ft lbs of energy.
100 grains shows 2052 fps and 1637 ft lbs of energy.
110 grains (max load) shows 2135 fps and 1772 ft lbs of energy.
Also Semisane.... I checked the see through powder measures I have. You are right. And they do throw light charges. I never knew that. The old brass pull out powder measures were so common for so long that I never questioned them.

Careful there Dave, you are starting to get my mentality on the powder volumes, more is better
Just as a side note... This is volume measure that I use and over time it has proved top be the most consistent and very close to weight....
But, Dave it only goes to 120 grains

I have three of those TC U-Views and find that they all throw light charges.
Using GOEX FFg as a base, one would expect a 100 grain measure to throw a 100 grain weight charge. However the U-Views average around 90.5 grain weight when set at 100 grains volume, filled to overflowing and cut off without a tap down. Tapping down the initial fill and topping it off again before closing the funnel yields a charge of about 94 grains weight.

Black Powder measures volume to weight most times. But I was using a volume powder measure to make my loads.
Sabotloader I have one of them also. And three see through, and two pull out brass measures. Plus there are measure in each of the possible bags I keep. I just hate to look for them...

Check out the link below SJAdventures. It will either clear it up or confuse you more. 
As a general rule, just remember that the theory behind volumemetric powder measures is that they are based on real black powder (probably FF grade) so that volume and weight are equal. So a 100 grain volume measure of FF black powder should weigh pretty close to 100 grains.

Cept for.... 100 grains of T7-2f, BH-209 and/or Swiss BP... they measure by volume to equal most BP's and BP subs but are able create approximately 15% more power than a 100 grain load of normal BP's and BP subs.
