Hello Everyone,
I have a issue to run by anyone that can help. So I've been loading some 45 ACP with W231 powder for about 8 months now (this is when I started using W231, since it was so hard to find for sometime now). I'm using a RCBS Uniflow powder measure with small cylinder. I've got a RCBS ChargeMaster 1500 Scale. Both pieces of equipment are about 15 to 17 months old now.
Here is the question..... I've been loading 5.2 Grains of W231 using my RCBS Uniflow powder measure. I've loaded about 650 rounds with this setting on the Uniflow powder measure. I haven't touched the setting on it, as I'm working on getting a stock of 45 ACP loaded up before moving back over to my 9MM setting. So this morning I figured I could load a few more up and I came across an issue that I can't figure out.
When I went into the reloading room (inside the house, in a bedroom), I did as always fill up the hopper on the measurer and drop a few loads and set them on the ChargeMaster 1500 scale as always. When I did it this morning the scale said 5.0 grains not 5.2 grains. I calibrated the scale two times just to make sure things were right there.
I haven't touched the setting on the measurer so it should be dropping 5.2 grains, but the scale is now saying 5.0 grains. When I was loading the other 650 rounds in 3 different load sessions, the scale showed 5.2 grains each time.
The only thing I can think of is the temp in the house if a little different from the other 3 load sessions. It's getting a little colder outside, so inside the house is a little colder not much though. The heat is on most of the time to keep the temp in the house at about 74 to 78 degrees.
Anyone have any ideas why it looks to be dropping 5.0 grains vise 5.2 grains now without touching the setting on the measurer? Is it the temp?
Thanks..
