    Has anyone done a head to head comparison of the Sierra 6mm 107gr MK and Berger 6mm 105 VLD Hunting bullets with respect to BC and accuracy?

    I am interested in results at 421 yards.

    I am in the market for a 6mm-06 build from a Tikka T3x and would be probably be shooting one of these 2 for coyote sniping at distance. Pass the popcorn!

    The results will depend on your skills at shooting and reloading. My 6br prefers 107SMKs with Varget and RL-15 running neck & neck for accuracy.

    Your barrel will tell you what it likes. My SLR with a 7.5 twist prefers the 110 SMK to Berger 105 hybrids, so that’s what I’m running.
    Not an answer to the question, but I hope it helps,

    My latest br barrell definitely prefers 107mk and Varget compared to any other combination... was easy to tune and shoots small, I use it for 400m and 500m benchrest. 10jump 30gns...

    Don't be afraid to put 107's in the lands, sometimes alot. You may be very pleasantly rewarded.

    Seems to be a minority response, that you are having success with the SMK 110's at all.

    I wonder if the 110 is just a little more sensitive to tune? It seems as though it should be an excellent bullet. I have a hard time believing Sierra would introduce a new bullet that didn't shoot.

    In my case I am doing everything I can to avoid a faster than 8 twist barrel although the .617 BC of the 110 is very tempting. :)

    The BC is just a number, like velocity. If it doesn’t shoot small in your setup, it’s wortless. Like a fellow shooter told me years ago. “those knobs on the sight, they are adjustable “.
