It's all perspective John. Did you move the shoulder back OR did you shorten the length of the case, from the shoulder to the case head, by pushing the case head further into the die? body gets shorter, neck gets longer. I know... semantics. Depends on which side of the tracks your from.
Well... I gotta give it to you.
You made me thunk some about this perspective thing.
First of all.. I didn't shorten the case - it is actually longer than is was, so there !!!
The real question is did the case go forward, or did the shoulder go backward. It is all that
relativity stuff (like cousins and uncles and incest and stuff like that!!!!).
OF course, once'd I realized that, I got a compass out and checked the direction my press was pointing in, and DAMN, if it wasn't pointing east. Now, as you probably know, sinch you are one of those old time semantics guys - the earth is moving, er... rotating east - about 500 miles an hour at my latitude. So, is the shoulder standing still, and the case moved forward, but just a bit faster, cuz it was getting a "Time-space continueum" thingie accelaration boost from my arm pushing on the handle thing?
I don't know - or maybe the bump is really a bump in the wormhole thing, and the shoulder got lost for a nano-nano-nano-second, and when it got free from the wormhole in the time-space-contineum thing, it couldn't catch up cuz the earth movement had a nano-ripple in it.
Ya' thunk it??????
