Michael MichalskiSizing Question - Curiosity Only
Sizing .38 Spl. on a RCBS turret press using a Lyman .357 TC die. Been doing so for many years and just lately noticed a phenomenon (?) that is bugging me. The resized case seems to be slightly warmer coming out of the die than when it went in. Only slightly warmer to the touch and definitely not even close to hot. I'm thinking 83 year old fingers are playing games as it is with other body and brain functions. I did not think tungsten carbide sizing created heat, not even slightly.
Any comments or similar experiences out there? Or just a senile old man ranting?
(or maybe I should run for president)

RapidrobFriction is friction. Depending how large the case expands to, there will me more or less friction.
Straight brass or plated brass?

buffybrJust out of curiosity from your post, I just put my RCBS .38/.357 carbide size die in my Rockchucker press and quickly sized 3 .38 spl cases.
My 78 year old fingers could not tell any difference in the temperatures of the cases before and after sizing them.

jeffeossoyes, might consider a little more lube, though
Of course it creates friction. Carbide or not. And with carbide you do not use any lube. That is the point of carbide dies.

eagle27An accurate IR surface thermometer may be more scientific in picking up temperatures changes. With age comes thinning of the skin, at 72 I bruise and tear skin much more easily now and how often do we hear the elderly saying "I feel the cold more now".
Maybe the OP is right, we elderly are more sensitive to temperature changes?

Lamarbend a coat hanger or stretch it and I bet it gets hotter too.
