I hope this isn't received poorly, but it's the truth -- and I hope you find it helpful.
I've got a much newer Taurus Model 66 and there's nothing it won't handle...so far. That's because there's nothing I won't feed it. Because it's a Taurus, I use it as my "feed 'er anything" .357 Magnum and, well, let's just call it a running experimental test platform.
I wouldn't subject my prized S&W 686 or my Model 19 a boatload of the hot 125's I build, but I'll feed a zillion of them to the Taurus.
Attention Brass rats and other reloaders: I really need .327 Federal Magnum brass, no lot size too small. Tell me what caliber you need and I'll see what I have to swap. PM me and we'll discuss.
