    Default 30 OR .311 BENCREST

    ITS OCCURED TO ME THAT A 30 BR REAMER WOULD LIKELY WORK TO RECHAMBER A 7.62X39 CHAMBER. I NEED TO OVER LAY THE REAMER PRINTS. I KNOW IF RAN IN DEEP ITS DOABLE.

    THE CONVERSION WOULD GIVE ABOUT 8 GRAINS MORE POWDER CAPACITY AN WOULD DRIVE 150 GRAIN BULETS AT AROUND 2500 AN WOULD BETTER A 30-30.

    YOU WOULD NEED A NON CHROMED BORE TO BE ABLE TO CUT IT.

    IF YOU WANTED A BETTER HUNTING WEAPON AN MORE POWER FOR ZOMBIES THEN THIS WOULD BE FAIRLY SIMPLE CONVERSION.

    I HAVE A OLD yUGO BARREL COMING ( I THINK) tHAT I MAY TRY TO CHAMBER WITH MY 6MM BR REAMER WITH A .308 PILOT AN THEN NECK AN THROAT IT WITH MY 7.62X39 REAMER. FOR A .308 BORE i CAN USE MY 300 SAVAGE OR MY 308 REAMER.

    I HAVE WANTED TO DO A 308 X 1.5" BR FOR YEARS THIS IS THE SAME THING JUST A 30 DEGREE NECK VS A 20.

    THE ROUND WOULD BE DAMM CLOSE IN PERFORMANCE TO MY 300 SAVAGE SET UP.

    FACTROY MAGS MAY WORK NOT SURE YET.

    I've read about people rechambering 7.65x53 Argentine Mausers with a .30-06 reamer, then using a .311 expander when reloading their '06 brass. I guess you'd call it a .303-06 or a 7.7-06.

    The interesting thing about that conversion was that you didn't have to cut, swage, and fireform .30-06 brass into 7.65, like I used to have to do for my Argie. Just use ordinary '06 brass and a .311 expander.

    My own ".311 Whisper" wildcat is nothing more than a .300 Whisper expanded to .311, just because almost all my rifles and some pistols use that size, and I have several spare barrels around in that size too. I don't expect any difference in ballistics, just convenience for my own personal situation.

    IM THINKING IF I DO IT RIGHT A US MADE 7.62X39 BARREL COULD BE RECHAMBERED .
    TO A 30BRX TYPE ROUND.

    A STRAIGHT 30 BR WILL NOT AS THE SHOULDER IS TO FAR BACK. BUT IF USE A BRX REAMER RAN DEEP ENOUGH THE CHAMBER SHOULD CLEAN UP. YOU COULD ACTUALY RECHAMBER AN EXISITNG BUILD IF YOU WERE CARE FULL AN MADE SURE THE HEAD SPACE WAS DONE RIGHT.

    I HAVE BEEN WATCHING EBAY FOR DIES BUT NO LUCK SO FAR. THIS IS KIND OF A SPIN OFF OF MY 6MM BR VARIANT. HMM 6MM BRV SOUNDS COOL?????

    YOU WOULD WANT TO KEEP THE NSHOULDER IN ABOUT THE SAME LOCATION AS THE X39 SO YOU CAN STILL SEAT BULLETS OUT OK.

    I SEE THIS IN .308 BORE USING THE NEW BULLETS DESIGNED FOR THE 300 BO AS A REAL DEER STOPPER . IT SHOULD OUT DO THE 300 BO BY ABOUT 300 FPS OR MORE. IT WOULD REALLY OUT DO IT WITH A 150 GRAIN PILL.

    HMMM CASE CAPACITY OF A 30-30 IS ABOUT 44.5 ABOUT THE SAME AS 30 BRX.

    THE 30-30 ALSO HAS A REALLY LONG NECK AN THE LOADE D CAPAICTY IS MUCH SMALLER. A 30 BRX LIKELY HAS MORE USABLE ROOM WITHT HE BULLET SEATED.

    IM SURE A 311 EXPANDER BALL COULD BE USED ON A SET OF 30 BR DIES. ALSO THERE ARE BUSHING DIES FOR THE 30 BR MAKING IT EVEN EASIER.

    IF A GUY WERE STICK WITH 125 GRAIN BULLETS YOU COULD MOVE THE SHOULDER AHEAD A LITTLE MORE AN GAIN EVEN MORE CAPACITY. USING A 223 MAG SOME HOW WOULD GIVE A LITTEL MORE LOADED LENGTH ALSO. MY 223 LOADS ARE 2.260 LONG SO IF A 30 CAL WAS LOADED TO THIS LENGTH THERE COUD BE SOME GAINS TO BE HAD. A 125 GRAIN 30 CAL WOULD BE A GOOD DEER ROUND OUT TO 200+ YARDS AT AROUND 2700 FPS POSSABLY. THE BC OF A 125 PILL IS NOT VERY GOOD HOWEVER SO ITS NOT GOING TO BE A GOOD LONG RANGE ROUND.
