#11462 Hodgson just released a new powder. It is CFE Black. It was developed for the 300 Blackout. Hodgdon's latest reloading manual lists loads for the 22 Hornet and K Hornet. Both of which have case capacities close to the 22TCM. I ordered some from Graf and Sons. I will post any significant results as soon as I can.

#11474 Let us know how it works out for ya, I'm real real interested. I'd not heard of the powder till your post. Besides my TCM I got a couple Hornet guns and a walking stick in .300 Blk. Thanks for jumping on it like a duck on a June bug.

#11568 FedEx will deliver the powder today. If someone is home. Has to be signed for. I plan on using it in both the rifle and pistol. According to the burn rate list it is slower than Accurate 1680. But very high density. So with the slower powders you can't get enough in the case to get a high velocity. CFE BLK is very dense. More powder in the case. Should be interesting.

#12311 Hey guys, first post here!

I just had a 14.5" AR upper built in .22 TCM and purchased a couple hundred cases from Sleeping Giant Brass as well as 1K Armscor 40gr projectiles. I heard the Armscor cases are soft and don't hold up too well, so I bought the Sleeping Giant cases because they are formed from once fired LC 5.56 NATO brass.

I will only be shooting .22 TCM out of my rifle for now, so I'm very keen to hear of experiences with the BLK powder!

Thanks,

Steve

#12319 I hope to have it next week!

I'll start a new thread about my AR.

In the meantime, I'd love to hear he testing results on CFE BLK. It sounds promising for use in TCM rifles! I'll want to have a few rounds loaded before my upper arrives.

Best,

Steve

#12419 Got to try out the CFE BLK this afternoon -- AP cases, Fed 205 primers, 35gr bullets. 16.4 grains fills the case to the top; 13.3 grains fills the case to the base of the neck. Two shots each charge, started low -- 10.5gr, velocity 1860 fps; 10. 7gr velocity 2108 fps; 10.9gr velocity 2140 fps; 11.1gr velocity 2207/2083; 11.3gr velocity 219 6/2208; 11.5gr velocity 2258/2195; 11.7gr velocity 2260/2240; 11.9gr velocity 2288/2321; 12.1gr 2400/2345; 12.3gr velocity 2423/2403. Primers looked normal, bolt lift OK. Not impressed with the velocities, especially with light bullets. On the up side, even with all the changes in powder charge, the point of impact didn't vary much. All twenty rounds were in a pattern around 2 1/2 inches at 100 yards, and I was not shooting for tiny groups at all. Down the road I will try some 40gr bullets just to see what they will do, but I don't think that CFE BLK is going to do anything exciting in my rifle. LilGun still reigns supreme.
