I have not sized them yet, but I took 10 BB LC as I got them, I have deprimed and cleaned them only.
I also took 10 BB LC brass which I have reloaded and fired once, deprimed and cleaned.
All 20 of them, when placed in the Sheridan gauge, dont go all the way in, (stick up about a quarter inch, and I have always noticed this.) the ones I have resized and fired once go in slightly further, and come out slightly easier that than first 10, which are as they came from BB, I deprimed and cleaned only.
Placing them in the Wilson gauge, The ones I got from BB and havent done anything to but deprime and clean, and the other 10 that I have reloaded and fired are very similar. The rims all stand proud like in the earlier picture, which I find typical for this gauge when I slide in a unsized fired brass.
The 10 from My gun that were previously reloaded and fired are slightly looser and fall out of the Wilson gauge slightly more easily.
Measuring them in the RCBS comparator, the first 10, which are as they came from BB and I have cleaned and deprimed measure like this: 1 piece measures 1.463, and is the longest. 3 are 1.462, 4 are 1.461, and 2 are 1.460
The 10 I have reloaded, fired (in my gun), deprimed and cleaned measure like this: 5 are 1.458, 4 are 1.459, and 1 is 1.460
Next I will size them and give new measurements. I removed the dies last night, so I will need to set and adjust them, which I will do with different brass, then I will size all 20 and remeasure.
Since you asked I size, shoot and resize and measure, I will concentrate on the 10 that have gone through my gun, the other 10 are just for comparison sake. I will take an average of the 10 that went through the gun and use that as target average.
It should be noted that ALL 20 came from BB, all 20 are circular crimp, (I find the 4 stake type can cause some odd measurements without further prep, so I avoided them, and all 20 are LC brass.
All brass, gauges, and dies are carefully cleaned.
