    The rifle comes with redding dies, I'll be sure to check them before use.

    The one thing I have been disappointed with is the fact that the chambering is throated for heavier longer slugs. I nearly pulled the trigger on a 6.5 TCU barrel when I discovered that it also is long throated. I would like a little shorter throat for light for caliber bullets (j words) as I am a varmint shooter.

    A long time dearly departed Cast Boolits member Junior1942 was a huge fan of this cartridge and he also wrote articles online about his work and experiences with it. A bullet he had good experiences with was the Hornady 154 gr. spritzers. My barrels liked also. I recall a ground squirrel I shot with my carbine barrel loaded with this bullet. No expansion but one very dead grey digger indeed.

    Junior 1942 went to work and set up a mini chop saw and lopped the nose off a bunch of those Hornady 154’s and found a resulting slug that DID now expand at 7 TCU velocities.

    VIVA the 7mm TCU!

    I'm going to try to duplicate Junior's 154 Hornady boolits.
    I've have a chop saw.
    I also just simply fire a .223 in my TCU chamber.
    Perfect cases.

    I really like the 7MM TCU as brass is cheap to free and can be reloaded many times. My favorite load for 25 yds. is 5.2 grains Unique with a 120 grain gas checked cast bullet. use in my Contender 10 in. and 14 in. and my Savage Axis with a Shilen barrel. Much fun!!!! dd

    Nothing is impossible for the person that does not have to do it.

    I just picked up a couple Contender barrels (10" and 14" bullbarrel) along with 4-500 pieces of brass, couple boxes of 120 grn J things and a set of dies recently in 7mmTCU. I'll probably sell the 10" off and stay with just the 14" to get a little bit more velocity out of the load.

    After reading this thread I am inspired to get mine out and play with it. I still have a couple hundred loaded up.

    You're going to love the 7mmTCU.
    Don't sell off that ten inch barrel yet!
    Keep it around.. I think you'll shoot it way more
    Than you think.
    I know I do .
    Cheer's!!

    I bought a 2nd sizer, back in the Day when RCBS Would still cut you a Special Sizer Die for a fair price and 3 fired cases. It works so well, that I Haven't had to form any new cases in years. But then I don't shoot it 600+ times a year either. And My loads are not as hot with cast as they were with those other types of bullets.
    I HATE auto-correct


    Happiness is a Warm GUN & more ammo to shoot in it.

    My Experience and My Opinion, are just that, Mine.

    Was at a local gun show this weekend and was basically handed a brand new sealed box of Hornady 7mm GC, so now I guess am on the lookout for a mould set and sizer/lube die for my Star..
