First of all “sir”, I am not stating this gage will control neck tension. It is used to "ACCURATELY" measure your shoulder bump back...please read what I posted a couple of times so you clearly understand!!!!!!
If you have never used this tool before you should keep your comments to yourself, as you obviously have no clue what you're talking about. You certainly "can not" push the shoulder back as far as you want to without damaging the case, any experienced reloader knows this!!!!
The Stoniepoint gage your eluding to is useless for getting an accurate measurement and yes, if you do push the shoulder back too far it does have an effect on the tension to some degree, as the die will bottom out on the neck.
Second of all, most dies have a expander button that is .002 oversized to account for spring back so that isn't new news!!!
There is nothing I hate more than people who feel the need to be arrogant with their comments to make themselves look good. Every time I post something, you have this need to contradict what I suggest. I have probably been reloading longer than you have been alive.
Why don't you find someone else to attack?
