Ammo life span accuracy

[Martini2]

Our hand crafted BP loads, carefully measured and assembled with TLC should outlast the maker IF stored in proper stable conditions. If in doubt perhaps an old shootist trick from another discipline (please don't jump on what might be considered blasphemous about loads that do not make smoke ;-) Back in day when High Power completions regularly filled weekends there was a lot old surplus Blammo being used up. It was not uncommon to run rounds threw a corresponding seating die to just barely "BUMP" the bullet seating to "break" any extra age induced friction. In some instances, if your hair is gray enough, you may recall GI issue rounds where bullets were sealed with black tar substance. Sorry if I digress, Point is if you are fortunate enough to load large quantity of fixed blammo before needed, rechecking the Over All Cartridge Length might be good practice. I have noticed some BP rounds now with GG bullets lengthen in time due to trapped air. It just adds to uniformity to inspect and compare older loaded rounds specs with loading info.
