    SO I like the idea of the 95 gr bullet. in the 6mm223.. for a little longer range..
    WAS THINKING ABOUT THAT. IM LOOKING AT DOING A BUILD ON A AK WITH ONE OF MY LAST 223 BULGY BOLTS AND I WAS GOING TO GO WITH A REALLY FAST TWIST 223 BARREL BUT THE 6MM-223 HAS GOT ME THINKING. IF I COULD SHOOT THE 110 GRAIN TARGET STUFF (NOT SURE A STANDARD 243 TWIST BARREL RE-CHAMBERED WILL WORK) AN STILL BE ABLE TO HAVE A GOOD SPEED ON THE LIGHTER 55 & 58 GRAIN STUFF I COULD HAVCE MAY CAKE AN EAT IT TO. IT LIKELY WOULD BE THE SIMPLEST WAY TO GO WITH ALL STANDARD 223 MAGS,BOLT, RAMPS ECT. JUST A BARREL CHANGE. AND THE PRESSURES STAY AT A KNOWN SAFE LEVEL ON A TWO LUG BOLT.

    IT DOSENT LOOK LIKE YOU GIVE UP ANY THING FOR SPEED OVER 223 IN FACT IT LOOKS A LITTEL FASTER ( I NEED TO REALLY CHECK APPLES TO APPLES HERE WITH SAME BARREL LENGTHS) AN THE WIND DRIFT IS BETTER WITH THE HIGHER BC BULLETS IN THE HEAVIER STUFF.

    WERE I SHOOT IN SOUTH DAKOTA ON PDOGS THERE IS ALMOST ALWAYS A GOOD WIND BLOWING . RANGING LONG DISTANCE SHOOTS WITH THE 75 GRAIN 223 BULLETS IS NOT SO HARD BUT DEALING WITH THE WIND IS. I WANT TO SOOT AT AROUND 800 YARDS AN ITS REALLY PUSHING IT WITH THE SMALL 223 CASE AND POWDER CAPACITY.
    I HAVE A FULL BLOWN 243 WIN SET UP IN THE WORKS ON A 308 SAIGA BUT THATS NOT A CHEAP ALTERNATIVE. I CAN REBARREL MY ALMOST SHOOT OUT 223 AK VARMNT RIFLE PRETTY EASY WITH JUST A BARREL CHANGE AN THINKING A 6MM-223 MIGHT BE SLIGHTLY BETTTER IN THE 300 TO 800 YARD RANGE. I RELOAD SO AMMO IS GOING TO COST THE SAME. HMMMMMMMMMMMMMMM

    I have a box of the 107 Match kings that I want to try, and that was the heaviest bullet I was going to use in my gun but.. It's gonna be really hard to get it into mag length in the AR magazine.. and powder capacity is also a issue.. I use H322 and H355 because it used less powder to get the same velocities.. I haven't done it yet.. as i have about 20 projects and other stuff, and no time to tinker.. these days.. The loads and bullets I've used was H322 23.5 Gr 87 Gr Hornady V/A max Loaded on 112/10/07 imr 4895 26 Gr 70 Gr speer TNT hollow point.. loaded 8/20/06 24 Gr H322 24 gr and 85 Gr & a 95 Gr Nosler Partition Soft point.. 2/23/09 B2B

    YEA THATS WHY IM THINKING ON Ak PLATFORM..

    I HAVE A IDEA FOR A MAG THAT SLIGHTLY LONGER THAN STOCK TO ALLOW A 2.70 OR MORE LOADED LENGTH. I WAS MESSING WITH THE 75 GRAIN AMAX IN 22 CAL AND WAS ABLE TO GO LONGER THAN A AR MAG WOULD ALLOW BUT A LITTLE MORE ROOM WOULD BE NICE. ITS A SHAME THE AR IS SO MAG LENGTH RESTRICTED.

    WHAT TWIST DO THOSE 107 GR MATCH KINGS NEED???????? i HAVE ABOUT 10 FACTORY 243 WIN M700 BARREL SITTING HERE THAT COULD BE RECHAMBERED. NOT SURE IF THEY WILL STABALIZE OVER A 100 GRAIN HUNTING BULLET THOUGH.

    IM THINKING THEY WOULD BE GREAT FOR A LIGHT WEIGHT SPORTER TYPE AK SHOOTING THE 100 GRAIN STUFF AN LIGHTER.

    WISH I HAD THE REAMER AND DIES. ILL HAVE TO START LOOKING.

    I'm not sure what twist rate the 107's need but if i remember right it has been a few years past. I ordered a 1-8" or 1-7 twist on my 6mm223 barrel.. at the time it was the ability to run a 90-95 Gr bullet at mag length and maybe 107 at single round length for the CMP matches but that didn't ever happen. I stopped shooting high power matches and mostly the upper just sat around.. as I was so busy with work I didn't shoot much.. I think I'll load some 107's up and see what kind of groups I can shoot with them.... .. B2B
