This could well be said to be in the wrong subforum, but this is about the only subforum I visit here, so here it is. The chronograph results I posted earlier sparked a couple private inquiries regarding the lightweight Pow'rball ammo, and discussions of lightweight bullets in general; as some of the more high-end exotic stuff uses VERY lightweight bullets, down to 60 grains for 9mm etc. This is the results of some personal testing I did several years ago, using extremely lightweight bullets in a couple revolvers. The thought was to try & replicate the old "Swat" ammo of the 1970's if anyone remembers those. They were just a jacket filled with expoxy, rather than a jacket filled with lead, achieving near-incredible velocities thru lighter weight. Standard disclaimer do NOT take this as me recommending everyone run out & try this. Its potentially VERY dangerous. Its potentially VERY dangerous. Im just experimenting for my own purposes, and sharing what I find; I am NOT trying to get others to follow my example. If you do, and you blow up your gun (or your hand or your face), its on you, not me. If this is violating any site policy or practice, or is just a cause of concern for any reason, any moderator is obviously free to delete any or all of this post; and I'll understand completely if that happens. Not trying to push the envelope of what's acceptable here at all, I just figured I'd share what I've learned so far. Don't mean to cause heartburn or worries for anyone.
