Adjustable powder measure

[vega]

I was wondering if this measure is accurate out of the box. The only place I can buy black powder requires me to shoot in their range too and on the day I will buy the BP. I don't want to bring along my scale for this purpose. And the technical specs says "This measure can also be used to load
black powder cartridges." Meaning it was designed for substitute. I have no idea how a substitute and the real deal looks like. BTW, this is CVA product.

TIA,

Since you didn't include a description, picture, or link to this product................I'm assuming you are talking about the standard brass powder measure that CVA sells??????

If so, that is exactly what you want to be using.

Do not, I repeat,................DO NOT use a powder scale to weight out your black powder charges. Black powder and it's subsitutes are measured by volume, NOT weight. Later on, once you establish your load with the volume measure, you can then weigh THAT charge and then you can use a scale to measure out the same amount. Most of the time, if volume measure a 100gr charge and then weigh it............. it will only weigh 80 to 90gr - so you can see that arbitrarily weighing a charge instead of measuring by volume could lead to disasterous results as you get toward the max powder range for a particular firearm.

As far as how substitute powders "look"................it depends on the powder. 777 is cut very fine for a given grade.............smaller than Pyro or Black. CleanShot (American Pioneer) is comprised of much Larger chunks than any other powder. These examples illustrate why we measure by volume, not weight.

This is what I have, for got to attached the link. Anyway, thanks for the informative details. I didn't realize that it was to be measured by volume.

Volume Measurement-

Mark Whiz is, to make a pun, "Right On The Mark" in what he says.

I'm pretty new to muzzle loading but using volume measurement only was the first thing my gunsmith impressed on me, heavily, knowing I do some centerfire handloading and have scales, etc.

He's a rendzevous freak, shoots in all the matches and at least 80% of his total business is muzzleloading, so he's pretty knowlegable.

"And the technical specs says "This measure can also be used to load

That looks like a standard BP/BP sub measure. Just because that measure can be used to for measuring volumn charges to fill BP cartridges don't assume that it's designed for BP subs. Note that there is at least one BP sub that is called Triple 7 that is slightly hotter than BP or other BP subs. You have to reduce Triple 7 charges by 15%. Also note that there are different granulations of BP and subs. The finer the powder, the faster it burns. The courser the the powder, the larger the firearm. A small BP pistol can shoot FFFG grade BP. A .54 bore longrifle takes the coarser, slower burning FFG grade BP. In subs like Pyrodex the little pistol would take Pyrodex "P" grade and the longrifle would take Pyrodex "RS" grade.

Hope that helps to clear some things up for you.
