View Full Version : 7mm TCU Mini-14?

Since it is on same case, could a Mini 14 be rebarreled to 7mm TCU? Would the cartridge length stop it?

Lavan, it would work. You'd just have to load your rounds to an overall length of 2.10". The 7mmTCU is 2.28" nominal. I don't believe that with the added barrel length you'd loose anything by seating the bullet deeper if necessary. George

I would have to disagree with you on this one, but only on one point. If you seated the bullet .10" deeper, what does this do to the internal pressures of the round in question. Would it be similar to adding .10" more powder? Cartridge pressure is a tricky thing and I would rather be safe than sorry. On the other hand, you could always try it and then fire the rifle from long distance with a very long rope on the trigger. If it blows up, at least you're still safe. Jim

Wallew, you make a good point. And I didn't express myself very well. I did say "load your rounds to an overall length of 2.10" but I should have said the load would have to be worked up. It would certainly change the pressures. There is after all only so much room in a cartridge case. George
