I have a great idea for those who firmly believe that tumbling will somehow create inert or dysfunctional ammunition-----don't tumble your stuff!
Do I think that tumbling will do that? How long will you tumble it? The Grand Canyon started off a lot less deep than it is today-look at what 200 million years of erosion will do.
Smoke one cigarette and you have very little increased statistical risk of lung disease-smoke 3 packs a day and see what you have develop over time.
Get my point?
Have I tumble cleaned up some of my reloads-YUP.
Notice a difference - NOPE
Will I tumble it for 3 weeks continuously- not hardly.
Everything in moderation guys.
