WELL I FINALY GOT ENOUGH TIME TO LOAD UP A FEW ROUNDS FOR TESTING AN GOT THE BARREL ASSEMBLY ON A RECIVER.
I DONT HAVE A GAS TUBE , GB , OR RSB ON IT BUT I WAS ABLE TO FINALY SHOOT A ROUND OUT IF IT . IT WENT BANG THE FIRED CASE LOOKS GOOD, NO GOOFY BULGES, FLAT PRIMERS, OR ANY ANYTHING WEIRD.
THE LAKE CITY 7.62X51 BRASS I USES HELD ABOUT THE SAME CASE CAPACITY AS A 6MMBR WITH LAPUA BRASS THATS THINNER . SO THE WHOLE BLOWING THE SHOULDER OUT ABOUT .100" PAST A NORMAL 6MM BR WITH THICK MILITARY BRASS GIVES ME ABOUT THE SAME RESULTS AS USING LAPUA BRASS AN JUST DOING A STANDARD 6MM BR. UN A UNIRE FORMED ROUND I HAD ABOUT 36 GRAINS WATER CAPACITY . THE BRASS IS REALLY THICK .
I USED JUST UNDER STARTING LOADS FOR A 6MM BR RIOGHT OUT OF THE BOOK AS THE CAPACIY WAS ALMOST IDENTICAL. HUGGED A TREE AN PULLED THE TRIGGER .
I SHOULD SEE ABOUT 43 GRAINS ON LAPUA BRASS BLOWN OUT .
I CAN GO A LITTLE DEEPER ON THE CHAMBER AN GAIN A LITTEL BUT WITH 95 GRAIN BULLETS IM GOING TO BE WAY DOWN IN THE ROUND WITH A 2.243 MAG WELL LIMIT ON A X39 MAG.
I THINK THIS ROUND WILL BE REALLY REALLY GOOD WITH SHORTER 80 APROX GRAIN BULLETS AS I CAN MOVE THE SHOULDER FORWARD AN HAVE THE BULLET STILL IN THE NECK.
I WAS ABLE TO FEED AT LEAST TWO ROUNDS OUT OF A FACTORY AMD 65 MAG WIH NO ISSUES . NOW ITS TIME TO GET ABOUT 30 ROUNDS CUT, FORMED , SIZED, NECK TUNRED OR REAMED , AN LOADED . I NEED TO GET MY OPTICF MOUNT ON IT . IMPROVE THE TRIGGER , GET IT RUNNING IN SEMI AUTO . BUT IT GOES BANG . SO HERE IS WORLDS FIRST 6MMBR??
AK 47. RECOIL WAS MORE THAN A 223 FOR SURE BUT WELL UNDER A
THE GALIL TUBE IS FOR MOCK UP IT WILL HAVE A STANDARD TUBE WHEN DONE . ITS A PISTOL RIGHT NOW AN WILL BE FOR A WHILE .
Well as tempted as I am to tease you about hugging a tree, Congrats on the test fire!
If you stand the cases in a pan of water you will not effect the case head hardness. I'd anneal them. I ended up annealing some of the 357ar cases twice before they were done, but that was going from 223 to 357. Can you neck turn them with a tight arbor to get them more concentric?
WTF are the pictures I spent a hour getting ready to post here . ERRRRR this crap is getting old !
