I'm thinking of adding a new Bbl. for my T/C and think I have it narrowed between a .30 Herrett and the 7mm TC/U. I'm reasonably familar with the specs on the Herrett, however, I'm in the dark on the TC/U, My primary interest is hog hunting, with the possibility of some handgun turkey hunting. Any alternatives to these 2 would also be of interest. If anyone can help me out here, I'd appreciate it. Thanks, Brad

Ballistically there are really close to the same, and in equal barrel lengths shooting bullets of similar weights, the muzzle velocities will be about the same (give or take a little). The differences amount to the differences in 7mm Bullets & .30 Caliber Bullets. The 7mm Bullets generally have higher ballistic coefficients, therefore travel through the air a little better down range given the same muzzle velocities. However the 7mm Bullets also have higher sectional densities which in turn requires a little more impact velocity to get them to expand. This can be, and is important to the Handgunner due to the lower initial velocities afforded by these cartridges in Contenders.

They are both Wild Cat Cartridges in which no factory ammo or brass is available. There are several steps required in making the .30 Herrett brass, and getting it formed properly for your individual chamber, while the 7mm T/CU simply requires running a .223 Remington case through a Full Length 7mm T/CU sizer die, then loading it to fireform the case to the chamber.

Both are mild to shoot, provide excellent accuracy, and have proven themselves in the game fields. Now, you did not mention what barrel length you are considering. If you are intending on getting a 10" Bull Barrel for the portability, either of these cartridges is probably the best choice in the shorter barrels. If however you are interested in a Super 14" Barrel, then the 7-30 Waters is a WINNER. Brass is available or easily formed, and this cartridge will reach out and provide greater range possibilities then either the 7mm T/CU or the .30 Herrett.

Good luck

I agree with Larry on the 7-30 if you're going to go with a 7mm. If you prefer 30 cal I'd say go with a 30-30 barrel instead of the 30Herret. The Herret's a good round that, IF I remember correctly, came out before anyone was making 30-30 barrels. Availability of factory ammo, if needed, and a generous supply of brass for either round make them more attractive.
FYI, I own a 7T/CU barrel for my Contender. I wish I'd just bought the frame and then bought a 7-30 barrel.

T/C Ammo...

Gentlemen, thanks for your help, sorry for not mentioning Bbl. length, I fell that I would prefer the convience of the 10" Bbl. I doubt that here in Fla. I would have to take a shot at the hogs or Turkeys at much over 60-70 yards, so it seems that either would serve it's purpose. Based on your response, the TC/U would be easier to form the brass. Thanks again for all your help to a T/C newbie. (Still haven't got to the range yet with the .22 match Bbl., but the weekends coming) Brad

I don't know anything about the 30 Herret, so don't take this as being partial. I do however have a 7TCU in 10". It shoots mighty fine and I like it very much.

You might want to check out this article

It was written a couple years ago, and the authors opinion has not changed. However the 7-30 Waters does perform much better in a Super 14 Barrel, but the 10" version was a winner also for what it is worth.

Don't get me wrong.. I LOVE. My 7tcu pistols.
Ten and super 14s....
But what really rocks is a 7tcu in a rifle.
I'm this close to (*) ordering me a MGM 23" 7TCU Barrel.
I feel the 7tcu is (for me) the best all around cartridge there is.
From squirrel to Deer.
It can do it all.

Only took me four years to add a 21" 7mm-TCU barrel.
☝😃😋
I finally found the old tapered 21" factory barrel.
With sight's.
T/c anything , is bloody expensive these days.

Yep, it's an old thread, but...
I like my 7 TCU as a carbine and I'd like to try 6mm TCU or 257 TCU, my real fave TCU's.
Conterders and G2's are a bad habit.

Florida allows suppressors for hunting... so I'll throw out a suggestion to eyeball 300 BO as well.

Based on 223 case and easy to make and reload for. Very small capacity so it sips at the powder jug (I'm using from 11gr to 21gr per round depending on bullet and desired velocity)

110-130gr "varmint" bullets that will explode out of a '06 or 308 at 2900fps+ can be pushed out at 2000-2200 fps from a 10" barrel no problem, and at that velocity they expand quite nicely and perform like a big game bullet on deer and such.

125-180gr bullets designed for the 30-30 can be launched at appropriate velocities so terminal performance can be easily predicted.

200-240gr big long bullets can be launched at just subsonic velocities, suppressed, and lay some serious thump for game like hogs and deer.

There are very light pistol bullets from 60 to 85 to 100 grains meant for the various .32s and 762 Tokorav or 762 Mauser pistol/SMG rounds. These can be pushed with tiny loads of pistol powder to either subsonic velocities and suppress even better than a 22lr for smaller game like rabbit, squirrel and turkeys OR can be driven to the point where even the Hornady 85 or 100gr XTP disintegrates on impact.
