If I actually get a spring breakup, I totally am trying this.
Live on a discrete acreage, easy to perform such things.
I like playing with metal. I'm a wood butcher though.
I've got a few scrap guns to play with.
Got some pieces from the 1850's through pretty much modern.
A few Bubba'd milsurps too. Do a WW1 Mauser or Ross, just to do it.
Be neat to dial it in and do a mixed load, I'm guessing the patterns would vary a bit.
Be a neat selling point if folks wanted to know about a certain era and you had a sample to show.
Really don't need the variety...case hardening is favored more for certain eras I figure.
Still neat to see it
Thanks for posting,
I'll be flagging this for further attention.
