The 10mm was initially pushed by the FBI. At the time, it appeared (on paper) to out perform the .45ACP and closely match, if not exceed, the .357 Mag. However, in actual shootings it failed to live up to the hype. Also, female agents had issues with the recoil, causing malfunctions in semi-autos. The .40 was born out of this and took off.

What Ammo can chad load that anyone else can't. He uses comercial bullets and powder. He is very good at what he does so maybe if you are not a competent handloader you should use commercial ammo, I will continue to tailor my ammunition to my guns, thats right you can get better terminal perfrmance if you match your bullet and powder to the gun and application you will use it for. As far as saftey and uniformity I would say my hand loaded ammo is as reliable, if not more so than his. He uses elctronic scales and powder deispensers(Very high quality and expensive ones at that) while on my ammunition that matters ie. hunting, long range target, and self defence I throw short and hand trickle to the right wieght on a beam scale and verify by rewieghing on another beam scale.

And back to the OP I use 357 mag 140gr FTX over unique, blue dot, or H110 depending on which gun it is loaded for and 200gr jhp over blue dot in the 45 acp.

Speer Gold dots and Winchester Ranger SXT, but soon i will be carrying some Hornady Critical duty in my spare mag, i figure that if i am in a bad enough situation that i need my spare mag then i better have some barrier punching stuff, and also if i get in a situation where i need that extra penetration then the Critical Duties should do the job.

Federal 9mm +p+ 115 grain jacketed hollow point. I shot 3 of these just for comparison purposes and holy hell. $39.97 about 4 years ago.

Black Talons!

380, 9mm & 45acp all have Gold Dot ammo, Federal HST would be my second choice and Winchester Ranger SXT a third in 9mm and 45acp.

9mm is black talon first followed by hydrashocks, pocket gun has a cci shotshell followed by cci hollow points, home defense usually just has some bird shot as I might use it in the yard for a randomn varmit also

My .40 gets Rem Golden Sabers or Hornady Taps. I recovered one of the Golden Sabers from sand and it was a nasty looking bullet. Excellent expansion and weight retension. The six petals of the brass jacket were protruding outwards with jagged edges with a good solid lead base in the middle. This would have made a nasty wound channel.

90 grain hydra-shok in my .380

124 grain Hydra-Shok in 9 and 90 grain Hydra-Shok in .380. I am a LEO and avoid loads that would penetrate sheet rock in an interior active shooter situation.

9mm Golden Sabres alternated with 115gr FMJ or 45 Golden Sabres alternated with FMJ.
(I do carry 5 mags though)

.357 sig Winchester Rangers or Gold dot

357sig Gold Dot

Has anybody tries the Hornady critical duty in 40 cal?

357 PDX

95gr 9mm +P C.O.P. (copper only projectile)

This bullet worked for me when I needed it. Had to defend myself at a point blank range. The detective said it was a picture perfect mushroom. It stopped the threat, passed fully through & bounced off the guy behind him that was attacking me as well.

*If anyone is wondering, I was not charged with anything & let go due to acting in self defense.

.40 Hornady critical defense....

Winchester Silvertips in .38 special +p are in my j-frame.

TAP, Hornady Critical Defense and Golden Saber
