I know I'm reviving an old thread, but I'm sorta dense at some things. For instance this bullet metal aging process. I'd been melting and pouring lead for 55 years before I ever heard of it. I was blissfully casting away for decades without a clue. And yes, I don't get out much! Ha!
But much like WilliamWaco, I'd cast, size, lube, and load in the same day at times or let 'em sit a spell and never noticed a thing. Then again, I wasn't looking for anything either. But I've had bullets go from the mould into a cartridge in a few hours and then to the range and was happy as a lark just to be shooting.
Now I had mentioned this aging/curing process to my loading amigo across the road. He's new at it since I'd only taught him how to load a year ago, but he's quite analytical. He said the same time occurs in moldings plastic. There's a cure time. Though much shorter. Now he put forth the question if curing time is a week or longer from the casting date, what happens if the freshly made bullet is processed and loaded? Doesn't it still continue curing while sitting in the cartridge case undisturbed? I said it sounded logical to me, but then again I only found out about this curing process last year. How do I know?
So what do you guys think? Reasonable? Ridiculous? Possible? You tell me. Remember, I'm a guy that casts and shoots in the same day and thinks Nothing of it.
