Stop it with your logicals.
I submit that if someone needs a second shot ready to go so quickly that they carrying a semiautomatic rifle, they are likely shooting at a decent-sized target that has a heartbeat, thus negating the need for a point zero zero zero zero one MOA group capability, unless gaming of course.

3D printed powder cup weight gain while curing?

So while I’m waiting for my Ingenuity Precision powder cup to get here from Oklahoma, I decided I’d try a couple of different powder cups to reduce powder bounce from my from my new IP trickler mount.
I’ve always had some powder bounce with the aluminum 419 cup and the IP trickler, even with the original mount.
But the Area 419 cup failed in a big way with the latest mount, bouncing powder everywhere. So I ordered the IP cup.
In the mean time I got an MK Machine 3D printed powder cup to try out and it was a failure, as far as powder bounce goes, too.
While I Iwas waiting for the next powder cup to get here I noticed something weird.
The MK Machine cup that weighed 245.08 grains when I got it now weighed 245.18 grains two days later. It currently weighs 245.22 as of this morning.
Way back since the ChargeMaster and later the Sartorious days, I’ve been writing my powder cup’s weight on the cup.
The Area 419 cup’s weight hasn’t changed.
Next up was this really nice Dead Drop cup I got last Saturday.
It weighed 924.56 grains when I got it.
This morning it weighs 925.66.
I realize the DD cup is a ceramic; the handle is printed.
The 419 cup’s weight has not changed.
Scale is calibrated and grounded, has a recently replaced power plug/ wall wart transformer and is connected to a line conditioner.
I have no doubt the scale is correct, because the 419 cup’s weight is a constant.
Humidity in this room is pretty consistent year round between 50-60%.
Anyone else experienced this? Do 3D prints gain weight while curing?
