Confusing Data

[pctumbleweed]

When I compare weight vs. Volume in reloading data I get different results. The difference seems to be in the published vs. actual weight of my Win 231 powder. Which is more accurate for use behind 9mm 115 and 124 FMJ?

I'm not quite sure what you're saying but I always go by weight.

Ditto. I always check and re-check the weight over the volume.

ever read a box of cereal or a product that says 'volume may settle during shipping' or
'sold by weight, not volume contents may settle during shipping.'
that being said i would reload using weight not volume

In the 20 plus years that your weapon sat under your bed unused, which ended only a couple of months ago, how many rounds did you actually reload with your own hands? How many rounds have you actaully reloaded in the couple of months since you started using your weapon again with your own hands? How many rounds have you yourself actually reloaded with your own hands in your entire life. It's a pretty good likelyhood zero is the answer to all three questions.

OP, don't be fooled by her ridiculously large post count. As you can tell, all the information EE posses regarding reloading came from the side of a cereal box. You would be wise to disregard anything she has to say related to your question.

Thanks to all who replied. Just to close this post I do use weight for my reloads. What I found was the 0.5 cc powder dipper weighed exactly 4.72 grains. This resulted in a conversion factor for Win 231 of 0.106 cc/grain not the published conversion factor 0.0931 cc/ grain. Surely the more dense weight could be the result of settlement but as the powder was poured from the factory container into the reloading powder container it is not likely due to "settlement" as suggested in one post. Again, thanks to you all for helping me on my first ever post to this web page!

Good luck tumbleweed. I found that using the scoops (lee) you can get slightly more powder in the scoop than you expect from slight compression. I also found that using the scoop will give you a lower-mid pressure round. I believe this is as-designed to give you a safe load. You can't overload when using the proper scoop with the proper powder as listed in your instructions. Good luck.

I am not responsible if you get yo'self blowed up.

Using weight is the best method. Weight is the only accurate way to relate "fire" power of the accellerant. Best example is aircraft. Jets use fuel weight instead of gallons or any other volume metric. A pound of fuel, whether temperature/pressure extremes make it a quart or a gallon, has the same burning power. For that reason jet aircraft fuel gauges register pounds of fuel and no volume metric.
