ALL OF THIS TALK OF 300 BO AN 308X40MM AN OTHER WONDER ROUNDS AHS REALLY MADE ME PAUSE AN THINK WY EVEN CONSIDER THEM FOR A AK???? ASIDE FORMT HE CHEAP BRASS WHAT ADVANTAGES DO THEY REALLY GIVE???? NONE REALLY OUT PERFORM THE ORIGINAL 7.62X39

YEARS AGO I PROPOSED A 308X1.5' BARNES AS A POSSABLE AK ROUND.

I STILL FEEL ITS A GOOD CHOICE AN CAN BE MADE USING 308 ,30-06, 8MM 243 ETC BRASS.

NOW IN RECENT YEARS BENCH REST SHOOTER SPURRED ON BY THE GREAT LUPIA 6.5BR BRASS HAVE BEGAN SHOOTING A 30 BENCH REST.

THE ROUND IS BASIACLY A 30x1.5 BARNES BUT WITH A MORE EFFECIAN T 30 DEGREE NECK VS THE 20 DEGREE OF THE 308 BARNES AN THE 308 WIN.

BENCH REST SHOOTERS ARE GETTING 3000 FPS OUT OF THESE IN HEAVY DUTY BOLT GUNS LIKEY WITH PRESSURES IN THE 60,000 PSI RANGE WITH LONG BARRELS. THAT SHOULD HOWEVER EQUIL ABOUT 2800 FPS OR SO IN A AK SAFE LOAD.

IM CURRENTLY BUILDING A 6MM BR VARIANT WITH THE SHOULDR PUSHED OUT AROUND .200 IT GIVES ABOUT 200 FPS OVER A STANDARD BR.

IM THINKING A SIMULAR VERSION IN SO CAL WOULD BE REALLY GOOD . ID EXPECT REAL WORLD SPEEDS WITH A 18 BARREL TO BE AROUND 2600 OR LIKELY BETTER. THIS IS A 400 FPS INCREASE OVER THE X39 .

I RELIAZE THESE NUBERS ARE AT WHAT SOME BOOKS SHOW A 308 WIN DOING BUT I KNOW THE BENCH REST GUYS DONT LIE MUCH. IF THERE GETTING 3000 FPS OUT OF A 125 GRAIN BULLET THEN ID BELIEVE THEM.

YES THERE LIKEY RUNNING HIGH PRESSURE AN LONG BARRELS AN ALSO SLOWER TWISTS THAN 1-10.

I JUST DONT SEE A RESON IT WONT BE A GOOD ROUND IN A AK. ONCE FOIRED 7.62X51 BRASS IS PRETTY REASONABLE. ITS CHEAPER THAN NEWX39 BRASS. YOU WOULD AHVE TO TRIM AN REAM NECKS BUT ITS ONLY THE FIRST LOAD AN ITS PRETTY FAST ONCE YOU GET IT DOWN . YOU HAVE TO DO T HE SAME FOR 300 BO AS WELL.
