I used to use a volume measuring tool with pre-marked increments on it and a plunger to adjust volume. After shooting a lot, a friend and myself both settled on shooting "105" grains (based on this tool). As my friend has gotten into reloading all of his ammo, last year we decided to weigh our charges with his fancy new scale to increase consistency. We discovered that "105" on the volume tool was actually 78.5 actual weighted grains (777 ffg). I know that all powders have different weights but I was surprised at how inaccurate the volume tool was. Anyone else compared volume measurements to actual weight?

Weigh it (smokeless).

I bet you could work up some more consistent loads by pre weighing them. I wonder how much difference it would make...

That's what we're doing now. I'm not sure how much it help, but it certainly doesn't hurt to have exactly the same amount of powder in every load, and it's easy to do if you have an electronic scale.

I pre-weigh and label 20-30 loads and have them ready to use at any time. It really makes it simple.

Pyrodex, and most other black powder substitutes, are formulated to be a volume-for-volume equivalent of black powder, not an equivalent mass-for-mass (weight-for-weight). Pyrodex is measured by volumetric measurement techniques, not in grains on a scale, due to the difference in density of Pyrodex versus black powder. For example, to measure a "60 grain equivalent" of Hodgdon's Pyrodex suitable for use in a muzzleloader rifle, one uses a volumetric measure that produces a volume of Pyrodex equal to the volume of a mass of 60 grains of black powder. Due to Pyrodex being less dense than black powder, a measurement by weight on a scale of 60 grains of mass of Pyrodex would be near a 30 percent overload.

Volume equivalence is a benefit in loading muzzleloading firearms, traditionally loaded using volumetric measures.

Triple Seven, unlike Pyrodex or Goex Clear Shot, is not a volumetric substitute for black powder. Triple Seven is, volume for volume, more powerful and users should follow load recommendations from the manufacturer.

Substitutes: Two of the many black powder substitutes are Pyrodex and Triple Seven. Both are available in granulated and pellet form. Use Pyrodex in volume equal to black powder; but when using Triple Seven, reduce your loads by 15%.

Measuring: Before loading a black powder product into a firearm, always measure it by volume and not by weight.

777 is not a powder you weight for shots - ala 100grains of powder. That is by volume, if you weight out 100grains you are shooting a MASSIVE load in a ML.

Buccaneer gave you the best answer as to why there is a discrepancy in the measured versus weighed.

As for measuring BP and substitutes I use an adjustable brass measure. It has a plunger you lower till the number on it reads the amount of powder you wish to use. Then you tighten a thumbscrew to lock it in place. Fill it from a flask until full. Then swing the funnel top over and it levels out the charge. Funnel is very handy for pouring too.

There are a few of them in here.
