I'd collected about a dozen or so early Remington-UMC .45-70 rounds, the brass appeared to be of the balloon-head type. Some fired, but a bunch didn't when I tried them in my Ruger #1S. No problem, I've been looking for some usable brass to try and duplicate a full-load .45-70 blackpowder charge, and I just can't get 70 grains of FFg into the newer Remington and Winchester brass and still seat the bullet properly.
The kinetic bullet puller got the big, hollow-base lead bullet out of the ammo. Cool, now I just gotta dump the old powder out.
It won't come out. It's one solid chunk of blackpowder after all those decades. Scraping with a small screwdriver just gives a few flakes. Hmm...
I've always gotten rid of surplus powder one of two ways - spreading it the lawn as a nitrate fertilizer, or putting it in a stainless measuring cup on a concrete pad, and lighting off a piece of paper towel stuck in the powder before stepping back several yards.
Ok, I set up the recalcitrant .45-70 round on my front entry sidewalk, stuffed some paper towel wadding into the top, and put a pinchful of IMR4350 into the wadding to give the ignition process some extra heat. I lit off the paper towel, and stepped back several yards to watch the short-lived Roman candle about to happen.
Save for one thing. It didn't happen that way. More like an M-80, or better, an M-100. Egad! The pressure wave was felt about the same time the ear-shattering Ka-BOOM happened.
My wife came running out of the house, probably expecting to see bits and pieces of me raining down from the sky.
Suffice it to say, old compressed blackpowder columns in vintage rifle brass can generate some pretty impressive blast effects.
The brass looked fine after the contents lit off, so it got soaked in soapy water like all of my blackpowder brass, and tumbled clean.
But I'll never do that again! Whew!
