Here's an interesting new-ish caliber that doesn't get much attention.


22 TCM - from Wikipedia

The 22TCM (Tuason Craig Micromagnum)[1] is a proprietary bottle-necked cartridge developed by Fred Craig and Rock Island Armory. Before the cartridge was commercialized, it was called the 22 Micro-Mag. Standard factory loads are 40-grain jacketed soft hollow point. Armscor has announced a new round the 22TCM9R which will be the same case as the 22TCM but have an overall length of the 9mmx19 round. The company plans to release this round in summer of 2015 with a Glock 22TCM9R conversion slide to allow the 22TCM to fit in a 9mm length magazine, hence the "9R" designation. The 22TCM9R will in fact still be a 40 grain bullet but will be a fully jacketed hollow point instead.

The 22TCM is based on the 5.56x45mm NATO case, shortened so that the shoulder is at approximately the same length as a .38 Super cartridge. The cartridge is designed to feed from a Para-Ordnance-style double-column .38 Super magazine. Currently only Rock Island Armory catalogs firearms chambered in 22TCM: a 1911 style semi-auto pistol (also available with optional additional 9mm barrel and recoil spring), and a bolt-action rifle (which reportedly can use the same magazines as the pistols); and only Armscor (the parent company of Rock Island Armory) manufactures ammunition.

Enjoyable read, but nothing that has not been posted here or in other places before.

I see reloading the .357 Sig as another myth. There is nothing more difficult about reloading it than any other round with the minor exception of using a smithering of case lube while resizing. It is often wise to do the same thing with a 9mm round to make resizing go smoother. I resize and deprime all my brass and run through the ultrasonic prior to reloading anyway. It makes the brass nice and shiny to help find it in the grass and woods while shooting out back. It also cleans the primer pocket.

The .357 Sig is much easier to reload in my opinion than the tiny .32 ACP.

I don't see the problem with the bump. The information is timeless, and there are people who frequent this site who don't always dig two years down to find extremely helpful information like this.

There are a ton or urban myths with respect to guns and especially with reloading. The firearms community,= unfortunately has a number of wannabees who repeat what they heard somewhere from someone they mistakenly assumed knew what they were talking about.

You're right about the .357 Sig. No harder or easier than most other things and I definitely agree about you with respect to the .32 ACP.

If you think that's tough, though, try the .25 ACP.

I wouldn't worry about it. It's a sticky for a reason. Even though it's had over 4500 views, there are still those that don't even see the stickies.

As to the dates - the information is the information. It's not just someone's opinion once you get down to the specific caliber data.

If one more person learns something that helps them make an informed decision - it's worth bringing it to the front again.

Thanks.
