Hi Fellow Members,
Does anyone currently own a rifle chambered for the 7mm TCU caliber ? In which rifle ? What is its twist and barrel length ?
If you do, please tell me about the different bullets you've tried. Which do you use the most ? Which weight do you prefer ? Would you build another rifle in that caliber if you were to do it again ?
Please don't anyone ask me why I'm even considering this as a new gun. If you have to ask that, it isn't very likely that you have that caliber in a rifle----in a Contender maybe.
Thank you for helping me.

Hi kdub,

Thank you very much for your info on the 7mm TCU. Now, that you've broken the mold, you could please consider some more questions as follows:
1. Did you anneal the brass before reloading the .223 cases with 7mm bullets?
2. Did you use the "lead dipping" or the "cases resting in the water" method of annealing ?
3. Did you chose the 10 inch twist, or was it made by Thompson Center and you took it "as is" from a seller ?
4. Who made the barrel ?
5. What action did you use ?

You have already been very helpful to me, and I again say, Thank You very much.

Mesa is a wonderful place filled with many wonderful people, My #2 son graduated from ASU, and I had visited there several times.

7mm TCU

Hi kdub,

I've taken a studius approach to annealing. I've read many reasons why those who used to anneal using your method have stopped doing so. Unless you ask, I shall not bother you with their reasons.

The one method I plan on trying was the method used by a custom-loaded-cartridge businessman who specialized in only wildcat calibers and annealing of hundreds of cases in an hour or hour and a half.

That method uses a lead pot set just at the melting point of the lead. The case has no primer and its primer pocket cleaned. near the melting pot ( here is the only dangerous part) is a container of water and ice cubes in it. Another container having only ice cubes to be added to the water later.

While holding each case inverted, with his fingers, he dips the case into the lead so as to cover the shoulder. Then he removes the case and gently drops it into the ice water VERY CAREFULLY. One drop of water into molten lead will cause you more anxiety than you'd ever desire ! Ran out of space.

:) :cool: Chuck
