I've forgotten more than u will learn about guns, hunting, shooting, smithing, reloading, count on that.
I believe it. Like you've forgotten the reality of the idiotic 9x21 caliber.
You've obviously
forgotten that the 9x21 that you constantly recommend is actually LESS powerful than the commonly-available 9x19 caliber. You constantly tell people that they're further ahead converting their gun to use a caliber that's not only unavailable almost everywhere
on the continent, but is also LESS powerful than the commonly-available caliber their gun started out in in the first place. That's some special genius right there.
Then again, I don't know how you could have genuinely 'forgotten' it, because I've reminded you of the fact
repeatedly; as recently as several times this year.
Simply put, the only reason the 9x21 even exists is to offer a better-than-380 option to those who live in places where 9x19 is prohibited. Its case is obviously 2mm longer than the 9x19, but its OAL is exactly the same, so your cartridge overall length is still limited to exactly the same. And its maximum allowable pressure isn't just below 9x19 +P, it's below 9x19
standard pressure. Whether loaded with lightweight bullets or heavyweight ones, the 9x21 NEVER exceeds a commonly-available 9x19 +P.
Please stop recommending the idiotic 9x21. There is NO circumstance where it makes sense for private citizens in north america. None.
