    I am considering switching to the 6XC. There is very limited info on this cartridge. I have the Berger manual but everything is set for the heavier bullets, (I use 87 gr. V-Max for prairie dogs). Limited powder choices. Also I didn't see anything on a trim to length. Searched all over the web can't hardly find anything. Does anyone know of a good info. source?

    I'm running 38gr of N150 with the 70gr BlitzKings out of a 20" barreled Blaser R93 (Custom Krieger 1:8 twist) and am making 3300fps. Well below max pressures and it shoots in the .3's. It's also a coyote, fox, and woodchuck killing machine.

    6mm-250 data is perfectly viable and available at hodgdon.com

    What is your reamer?

    I am going to order a 60 fb from Manson specifically for the Sierra 60 to 80 grain bullets just for varmints. Trying to get David excited about a varmint 6xc but I think he is a high bc guy. I am a speed explosion guy.

    I sent Dave Mason 6XC dummy rounds for the bullets below. He said the freebore would be .055"
    Berger 87grn VLD Hunting Bullet - Cartridge OAL = 2.634"
    Berger 88grn High BC FB Varmint - Cartridge OAL = 2.666"
    Berger 95grn VLD Hunting Bullet - Cartridge OAL = 2.679"

    I also sent him a 6XC dummy round with a 87grn V-Max bullet. He said the freebore would be .085"

    55 fb would be perfect for me. The 55 would be great for the 60 sierra hp if you ever try it. Or the 70 TNT and 70 Varmegeddon.

    The 88 berger fb is very long. I would really think you would need more than 55 fb for that one.

    My rifle was done with a standard Pacific Tools reamer, cut to SAMMI Specs, nothing fancy. The barrel maker usually rents the reamers for jobs like mine.

    When your 6xc varminter project becomes a reality, depending upon the twist rate you choose, let me recommend you try 4 bullets for varmints, predators, and up to deer. The 70gr NBT, the 75gr Vmax, the 80gr Sierra Blitz, and the 85gr HPBT from Sierra. I went the route of a 10 twist for my walking varminter and just enjoy it immensely. JME, YMMV. WD

    The 70 Varmegeddon and the 80 Blitz are both awesome.

    I am pretty sure I can get the 6XC with the small rifle primer to throw a 70 grain at 3900 fps and a 80 grain at 3750.

    Man that would hit a groundhog like a hand grenade and should have a very good barrel life with the right powder.
