Now that the weather is getting nicer I should be able to start reloading again soon.
Summers with 100+ degree heat don't leave me with much desire to go out to the garage and start loading rounds.
I need a new steel plate, the old plate is now so cratered from various different loads that it's hard to see what effect it's having. The plates weigh in at 45 pounds if I remember correct and they are at a hardness some where between the mild steel I'm used to shooting and the few hardened steels I've shot. I also want to get a THICK chunk of aluminum to see what kind of holes I can put through it, something like a 2 inch thick piece of aluminum stock but it's so expensive that I doubt I will wind up doing it.
One of the things I clearly remember not even being able to make a dimple on are some old leaf springs out of a heavy duty truck, the spring leafs were maybe 1/4 inch thick and I had them braced very well. M855 or M193, it didn't matter as neither left much of anything, the steel tip of the SS109 barely made the slightest dimple.
I'd love to get that stuff again and pit my 300WinMag loads against it, from a safe distance hopefully far enough away to survive deflection.
I've put regular M193 through steel up to 1/4 inch thick from around 50 yards away, pretty wimpy stuff. And I just don't have much desire to get M855 for anything when it's so expensive and at closer ranges M193 appears to hold an advantage thanks to it's velocity edge.
Eventually a 50BMG is making it's way into the stockpile, that will be an entirely different ball game. 2-3 inch thick mild steel will probably pose no threat while my guess is that 3/4 inch armour rated plate will be right about it's limit.
