WHY do we resize shotgun Hulls ....... and please ignore the obvious matter of depriming, which just happens to occur in the same single action of sizing and depriming, because depriming is not what causes me to ask.
If reloading brass likely to be used in a different centre fire rifle from the rifle which has just "fire sized it," then obviously to allow ease of chambering in the different rifle. BUT I am told that if that brass is ONLY EVER to be used in the rifle that just fire sized it, no need to resize as the brass has just been "fire sized" and is now the correct size for chambering in that rifle......For ever until it develops a fault /flaw and is discarded?
OK. So if shotgun hulls are to be reloaded and ONLY EVER used in the shotgun which "fire sized them," why when reloading the hulls, resize the metal bases of the hull as they are already sized for that gun? Again please ignore the obvious matter of depriming which just happens to occur in the same single action of sizing and depriming.
Depriming is not what causes me to ask. What does is that I am having grief with reloading Blue Rio 12 bore with their 3/4 inch high metal bases as they hang in the resizer tube of my MEC 600 junior and despite my best efforts and advice from Brian of Te Puke, no way can I "tweak" the MEC 600 junior to just resize and drop the hull.
Which in a "light bulb moment," caused this stupid boy to ask himself why the hell am I resizing them when they were not going to be used in another gun apart from that which had just "fire sized' them?
Seems to me that what is applicable to 12 bore plastic paper as regards resizing hulls should be no different from resizing centre fired 303 brass if the load is to be fired from the same firearm.....or am I missing something?
Please do tell.
