I've been using a CVA 4 in One T-Loader to measure my Blackhorn 209 powder. The cylinder is graduated and marked.
This week I bought a pair of Traditions Magnum Quick Loaders for in-field loading. These are also graduated and marked.
At the range today I filled and used all 3 cylinders with 100gr of powder. I noticed I was getting hugely different shot results.
I decided to measure 100gr in the CVA and dumped it into the Traditions cylinder. It came out to 120gr!!
I don't know which is accurate (but am basing all my shooting on the CVA.)
Anyone else seen such a marked difference in tube calibrations?

after getting a digital scale & seeing what a few grains of powder will do I will never use nothing else. shot to shot accuracy is great, I haven't weighed any pellets but I don't see them being very close, amazing what a few grains will weigh

I have the TC clear measure that looks like a syringe. I would never use a speed loader to measure my charge. I have a Traditions speed loader with graduated markings and its WAY OFF.

My speed loaders are approx. 30gr off of what they say they should beó80gr on the cylinder is actually closer to 50gr.

Blk powder was never meant to be measured by volume. Too inconsistent. More manufacturing hyperbole. Its sold by weight....not volume. Use a good scale and see the difference.

This is not true.

Blackpowder for centuries was measured by volume.

But it wasnt MEANT to be. Its sold by WEIGHT.. Not volume. Pour you several charges by volume, then weigh each one. All different.

Hey Lance- I did the same thing. I've come to the conclusion that the Traditions tubes is for pellets, not powder. Could be wrong but I think I read it somewhere after I discovered this.

I have to repair a broken solder connection on my scales, then I will weigh the charge out.
In the mean time, as long as I load the EXACT same amount, from the same tube, each time, I'll be fine.

New info, other than my soldering skills suck.
I filled both brands of graduated cylinders to the 100 volume line and then measured on electronic scales:
CVA TL Loader was 81.7 grains
The Traditions Magnum was 64.5 grains.

So, BOTH were off. According to Blackhorn, 100 volume should be 70 grains.
The 81.7gr has been shooting fine, so I am sticking with that.
