I made a pretty good haul this weekend from the grandfather of one of my students who is getting out of reloading. A sealed cardboard keg of bullseye, about a copy paper box worth of mostly rifle brass in 20 round boxes, and over 200 lbs of cast boolits, almost all of which are beautiful! Even some heavy 30cal hollow points which may make there way into some subsonic 300 BO rounds for filling the freezer this fall!
Amongst everything was roughly 800 125gn Prot X Bore boolits, complete with what I've now found to be the zinc washer gas check. I've been doing some ready on the whole concept that the bore is supposed to get coating in zinc, which I don't really like the sound of. It sounds like they were an interesting solution for the time but I don't really like the idea of coating my barrel in another metal, be it lead or zinc.
I'm torn between melting them down and skimming the zinc (temp control obviously), tumble lubing them as is (but I don't know if that will prevent the zinc getting onto the barrel) or Hi-Tek coating them (would it stick to the zinc?). Thoughts?
