What mainstream cartridges

[Quintus Poppaedius Silo]

.25 ACP, .32 ACP & .410 come to mind right away.

It is easier to pick ones I have use for.....

.308 Win, .223, 9mm, .45, .38 / .357, .22, 12 and 16 Gauge.

For me the rest are useless.
But I noted that a lot of folks have use for ones that I don't. Thats great as it is what makes the world go round!

The .40.

I just don't really like how it feels. Shot it out of a variety of platforms, weights, sizes, etc.
But I just like either the .45 push or the 9mm bounce. Just really lukewarm on it.

I think the .223 is a waste. If I can't kill it with a .22mag, then I'll get it with a .308.

.380, 10mm, .40 S&W, 30-30, .243 and .223 just to name a few.

I prefer the .22-250 to the .223, and the .243 is too close to .22 cal to be any good. If I want a bigger gun I want it BIGGER. As far as the handgun rounds go, I'm not a huge 9mm fan, but it has it's place. A compact 9mm can be a little more easily concealed. .380 is just too small, and anything larger should just be .45ACP.

I dunno, there are plenty that I wouldn't buy. But I can't imagine a single caliber made that I couldn't find a use for or that I wouldn't enjoy shooting if I had a gun chambered in it.
