So yeah... I finally got the stuff to load for the rascal. Very interesting and fun stuff. I finally goofed up with my chargemaster combo though, and I forgot to close the drain spout like an idiot and found H322 all over my table, so I had to clean that up.
I started at 24 grains, and worked up in .2 grain increments eventually until I got to 25 grains, maximum being 26. The only time I didn't work up in .2 grains was when I got to 24.4, and went to 24.8 so I could load the last 4 with 25grs. to equal a total number of 20 cartridges. I found myself trying to find powders that wouldn't wind up in a compressed charge, but it seems like 25 is pretty much almost compressed, with the bullet touching the top of the powder. H322 seems very bulky, and a minimal amount of powder equals a very large charge rate, which my scale was on because I checked it, just the nature of the powder.
The bullet in the cartridge on the left is not crooked, just the way the picture looks.
Hopefully these shoot good, and fire in the first place. I've heard these thompson centers can be fussy sometimes. I should have videos and a range report Wednesday. Hope y'all enjoy the vids!
Nice set up you got going there. Never seen that cartridge before, but that gun makes me want a TC :/
Digging the last video there. Looks like you had a lot weighing on your mind...
It's a wild cat, and its an interesting one.Originally Posted by Dill45
What kind of performance can you get out of the cartridge?
It just depends on the powder and weight of the bullet. The 7mm TCU was one of those cartridges guys used to knock the rams down at 300 yards and stuff in IHMSA (I think thats correct?) competition. You can expect anywhere from 1500-2000 FPS depending on bullet weight, and barrel length. Def good enough for inside of 150 yards deer popping.Originally Posted by Dill45
Those are some numbers to put up!
Good scope on that and you could do some real long range pistol shooting.
Yeah. That was the whole point of the cartridge. To fill in a gap in the long range pistol silhouette world.Originally Posted by Dill45
Any idea on the recoil? I know a 223 isn't that bad, but...this is a 7mm pushing a bullet that weighs at least double that of a .223 and with no muzzle break. Might be a good kicker.
I know a guy at my range that shoots a T/C in 30-06, and boy does that thing recoil. Has a muzzle break so the muzzle flash and noise are something to be witnessed but that gun seems like an angry bull.
From the charts, about 10 pounds of recoil so about like a 44 mag.
Love my TC's!
I doubt that you'll have problems making her shoot, but if you do, search for Mike Bellm's website - he is a wizard with these things. (would post the link, but can't remember if that would break a rule on this site or not).
