Super Silvertip
Just a nickel's worth here...
The Winchester Silvertip is a pretty good round. Even though it's not loaded to full Super potential, it's not exactly anemic, either.
I've chronographed the round at an average of 1150 fps from a Commander-length barrel...which would probably put it solidly in the 1200 fps range from a 5-inch barrel. That's low-end .357 Magnum territory, and a near ballistic match for the Remington reduced 125 grain loading. Not too shabby.
Expansion testing in gelatin and wet-pack newspaper showed good expansion and more than adequate penetration, even when quarter-inch dowel rods were inserted into the gelatin blocks to simulate a rib cage. The round is much more pleasant to shoot than the hot Cor-Bon 124-grain loading, and no doubt, much easier on the gun. It's also a little less costly than the Cor-Bon.
I'd say that if you can't solve a problem with a mag full of Silvertips,
you couldn't likely solve it with anything in a handgun.
Cheers!
