"Could someone here do a simple test for me. Hopefully you have some unique powder. All I want to know is if you measure 8 gr. Of unique on digital or balance beam and then pour that into a 45 colt case how far does it fill the case?'
Ok, I managed to do a bit of measuring.
I took an empty case, using calipers for all measurements.
OAL of the empty case; 1.294
Internal depth of empty case; 1.118.
Added 8.0 grns of Unique.
Depth from case mouth to top of powder; .720 approximately. (powder can shift a little or depth stem can be a tiny bit off.)
So, 8.0 grns of Unique filled up approximately .398 of the case. Of you round it off,, (remembering that the stem could have been off a tiny bit,) you get a fill of .400 in round numbers.
