Geez Melvin I got an average of 1,537.8 fps out of one of my 165 grain .400 CorBon loads, with 7.7 grains of Unique. .400 CorBon is a much simpler conversion. I'm sure even you could learn how to change the barrel in a Colt Government Model.

Heard of it, but not really interested in it. The .357Sig basically duplicates that with ammo that can actually be found places other than the internet, and I'm not particularly interested in 357 sig either, for that matter.

I get more than 85% of that power from the 9mm Corbon 100-grain load (measured out of my G19), in a caliber that's one of the most common on the planet. I like to actually use my guns, a lot of time just for entertainment purposes, and a common (ie, inexpensive) caliber is very good for that.

If someone wants to have calibers for experimenting & playing with, more power to them. I do that to a limited degree with .357 magnum and .454 Casull, especially from carbines. But my serious guns, I want in calibers that are inexpensive and common.

corbon ammo can no longer be had, John, even before the virus. The company is dead. As for the 357 sig, and the .400, she has no .40 or .45 assemblies, just 9mm and aint buying any, either. His site doesn't show barrels for the 960 in 1911, just in glocks. Wonder if it's inadvisable? I've shot him an email question about that. I'd never pay the $200 for a barrel. I'd get a spare 9mm barrel from somebody for $60 and deepen the chamber. That's all he's done. Dont even need a lathe to do that. You can hold the barrel in your hand and use a hand held drill for no more material than you're removing. Cooper's Super 9, based upon reamed out 223 brass in a .38 super barrel, got 125 grs to 1750 in a 6", That's considerably outperforming the 960 rowland. Even if you cut the barrel to 5", you're still talking 1650 fps. way beyond what a 357 gets in the same sized gun (ie, 3" barrel, 1400 fps, at best) I have no interest in any of it. The 9x21 was of interest in order to get top speeds in the 3" barrel of the little Sig. I dont want heavier bullets in a 15 oz gun. It's already all she can handle. The blast and flash of the 45 gr, 2200 fps load are horrendous. The spare barrel for the sig was almost $300.

Melvin, look back to the history of the 20th century, millions of people were shot and died because of standard full metal jacket ammunition. I'm not saying that wildcat cartridges don't have their place, but you keep peddling this bs that there is a "holy grail" of calibers. There isn't one. Shot placement is even more important than the "wonder bullet" that you choose. Given the current events that are going on in North America these days, the old army saying of "Keep it Simple, Stupid" makes more sense. If this pandemic and shut downs last for any length of time, the only people still shooting might be those that use cast lead bullets.

True. My point is that it's a caliber that is sold through normal outlets, even if that particular load isn't; and there are other loads that perform similarly from other makers.

Whether I want a 450 ft/lb load, a subsonic load, or whatever, the 9mm is one of the more versatile calibers available simply because of market forces, and that's the biggest downfalls of uncommon calibers. I do like the 22TCM, but it's between the .357 sig and 960 or 460 rowland availability-wise. It's just not common enough to be readily available.
