    What are yall's thoughts on the .357 SIG necked down to .251 caliber ? You could load 25 ACP bullets for it. I imagine a 50 grain XTP at 2,000 fps or so would really knock the socks off a wood-be murderer.

    Similar to .22 TCM and .224 Boz.

    Not a bad idea, it may have been done but I didn't find it quickly. .357SIG I think is a .40 necked down so people may have gone that way also.

    I think 357 Sig is good as is.
    Glock 35 with 357 Sig Barrel
    125 Gold Dot @ 1,399 fps / 543# KE
    125 HST @ 1,415 fps / 556# KE
    125 Ranger T @ 1,428 fps / 566# KE
    125 PPU FPJ @ 1,461 fps / 593# KE

    As a whole, is there any real use for hyper velocity (1800+fps) handgun rounds ?

    If small and light I would think varmint hunting may be about it. Or, some target sports. For defense I think there are better, available options.

    Pretty much my opinion. I have a 5.7. Great groundhog gun. I use .40 or 10mm for SD.

    Don't know how well the penetration would be with a hollow point, but I think necked down to a .32 would be better as it's a bigger bullet. Would be like 7.62x25 Tok, but shorter.

    Are there are lot of quality .25 caliber defensive bullets you can choose from?

    There are lots of 9mm defensive bullets available and an awful lot of technology invested in their development.

    I would be over the moon for a 224boz loaded with heavy 80gr bullets. Less drop than any other handgun bullet, better coefficients for less windage at distance... but I love shooting handguns at rifle distances so it's a pretty esoteric desire.

    They look at ya pretty funny when you line up to take potshots at the 450yd gong at the range with a 1911. They look at you even funnier when you start dropping them within a foot or so and walking them on target...

    Hunting at distances over 50 yards and defeating body armor.

    Soft armor can be defeated with a handgun if the caliber is small enough, the bullet tip sharp enough, and the velocity high enough. I do not know of any straight wall handgun calibers that can defeat soft armor that aren't mega magnums like .454, .460, or .500. I also do not know how well some of those lightweight solid copper Lehigh bullets do against soft armor when driven to a higher velocity. IDK how much effect projectile weight has on soft armor, but I've long believe that defeating soft armor has to do with velocity and sectional density.

    Which has me wondering if something like .327 is capable of defeating IIIA soft armor because it's a smaller diameter and out of a 4 inch barrel is capable of hitting 1600 fps.

    I made some 90 gr varmint loads for .357 Sig that are pretty snappy. I had to use Bullseye powder since I wasn't getting complete ignition with AA#9.

    32 NAA is about as close as i think you will find. 380 necked to 32. I find it a really intriguing little round. I think it would make a neat trap-line type revolver; small caliber but 6" barrel.

    60gr @ 1200fps from a 2.5" barrel
    60gr @ 1450fps from a 4" barrel

    80gr @ 1000fps from assumedly a 2.5" barrel

    A 10mm necked down to 32 would make an interesting round. Similar to 32-20 but shorter and higher pressure.

    .32 NAA sure does sound like a handy little cartridge. I bet it'd make a great short range bobcat and fox round out of a little 16in bbl bolt action rifle.

    I would think so. And it would fit in a magnum rimfire sized receiver. Im envisioning a marlin 25 action in 32naa. That would be a really handy rifle.

    It would reliably take down anything under 50 lbs. The 60 gr projectile penetrates about 7 inches and expands to a bit over a half inch with about 70% weight reduction. It was designed side by side with their guardian pistol (seacamp lookalike).

    The best round for harvesting pelts is one that makes a tiny entrance hole and no exit hole.
