22 TCM - Powder?




Fred Craig (inventor of 22 TCM) supposedly recommended 9-10 grains of H110/W296 for reloading the cartridge (I've been using 9.8g with success), but I noticed that quite a few folks on this forum (and others) have gone beyond that in hopes of matching the factory rounds.

Out of curiosity I took a factory 22 TCM cartridge and opened it up - wanted to see how much H110/W296 they used. On my scale, it measured 9.38 grains - much lower than what I expected. Then I noticed that the powder does not look anything like H110/W296. See picture below:

H110 on the left, the powder from the factory cartridge on the right. Definitely not the same. Interesting that what was recommended for reloading is not the same as what Armscor actually uses in factory loads - could they be using powder that is only commercially available? I don't know what this is, but I'd definitely be interested in finding out! Thoughts anyone?

Oh, Lord; don't tell me the Unobtanium folks have gone into the powder business also?

In other cartridges, I've found that lil gun gives more velocity at lower pressures with similar charge weights.

Will be interesting to see what they use also. I am using 10.8 H110, anything much less and the casings just dribble out of the gun if at all.

I sent an email to Armscor, have no idea if they will answer the question. I've gone as high as 10.4grains , but no further so far. It is already so loud/fireball so big that I worry about my fingers....how does accuracy at 10.8 grains compare to loads in the 9.8-10.1 range?

I've read other posts about Lil Gun in 22 TCM. Supposedly it is generating velocities in the range of 2300 fps or higher! Yikes!

I'd like to try it with AA #9....or to be honest, I'd like to see someone else try it and let the rest of us know about it with well documented load data

At 10.8 H110 accuracy is better than I am. Factory ammo averages 2058fps and my reloads using the 10.8 averages 1949. Casings land in about the same location. The 10.8 load is good enough for me and one that I will stick with. Works on prairie dogs.

I have a jug of surplus powder that says to use h110 data. That powder looks like the one you posted. It was supposed to be Chinese, PSA is the only thing marked on the jug. I have only tried commercial h110 in my tcm though. I would like to try aa9, 2700, and something faster burning. I was loading the speer 33 gr hollow point. Lots of unburnt powder stickian up the chamber.

Armscor told me to go ask Fred Craig. Not sure why I would ask him about the powder that ARMSCOR is using....maybe they do not want us to know that it is Meistermash's surplus powder?

Ok I had a chance to look. I lied. The jug I have got is marked WC820 use h110 data. The psa marked jug is supposed to be 3031. I have a couple of boxes of factory loads bought at different times. I'm going to pull a couple of those down just to see.

Most factory ammo uses powder that the public can't obtain.It defintly explains why most people aren't getting close to factory velocity.

I know the 22 TCM is only made by RIA but you guys will have better luck posting any reloading ?'s in the reloading section.
