Case forming is not fun for me either. Shooting a completed wildcat that you made from start to finish is though! I have been thinking about some builds based off of the x39 case or the 5.45 case, but alot of people have been making the 5.45 out of 223 cases so perhaps I'm close enough with the 223 case.
I got a hold of some YUGO bolt hold open mags an they dont have the bumps to stop the followers it looks like these will work better as the shoulder will not the bumps that are on a standard mag.
IS THERE ANY SOURCE FOR BHO FOLLOWERS???????? ID LIKE TO MAKE A FEW 10 ROUNDERS ???????????
1000 rounds of military LC 7.62×51 primed unfired pulled down with sealer on the neck brass arrive today. It should be perfect for this project as well as all my other 308 based rifles
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
7.62X39 .
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 .
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?
