    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
