6.5X47LAPUA PROJECT

[BEN BRAND]

NEED SOME ADVICE ON THE 6.5X47 LAPUA. I AM FROM SOUTH-AFRICA AND HAVE ONLY SOMCHEM POWDERS TO WORK WITH. I READ WITH INTREST ALL YOUR POSTS ABOUT LOADS AND SPEEDS YOU GET WITH THE 47 LAPUA.
I WOULD REALY LIKE TO USE THE 139 SCENAR ,WITH THAT BULLET WEIGHT I CAN PRACTICE PAPER SHOOTING AS WELL AS HUNT WITH IT, I THINK 139GR WILL GIVE MORE THAN ENOUGH PENETRATION. BUT IN THE SAME BREATH I THINK THE 123GR SIERRA OR LAPUA MIGHT GIVE BETTER TRAJECTORY.IF I WOULD SHOOT BOTH GRAIN BULLETS WHAT DIMENTION REAMER DO I NEED. WHAT TIPE OF BARREL WOULD YOU USE, I HEARD THE PACK-NOR BARRALS IS THIGHT, AND WOULD WORK BETTER WITH LAPUA BULLETS, IS THER ANY PROOF IN THAT. HOW LONG SHOULD BARREL BE FOR OPTIMUM PERFORMANCE. ANY OTHER TIPS REGARDING THIS CARTRIGE WOULD BE APRECIATED.IF I COULD GET THE SAME RESULTS AS ERIC CORTINA I WOULD BE VERY GLAD.
I REALY DONT WANT TO MESS-UP THIS PROJECT.

THANK YOU

PS. SORRY IF THERE IS ANY GRAMMAR OR SPELLING MISTAKES.I AM AFRIKAANS SPEAKING

GOEIE DAG

If you want to get the same results as Erik Cortina, maybe you should try contacting him. ;D

PM me your gun information, I know you are just going to build it, but tell me what would be the main purpose of this rifle and how much you would the weight of the finished rifle to be. Also tell me how far you will be shooting and at what.

According to QuickLoad, Somchem S365 would work very well with the Lapua 139gr Scenar seated to a cartridge overall length of 2.754 inches. You could probably start off with 35 grains and work up carefully from there in 0.3 grain increments. S355 should also work but your maximum velocity would probably be about 150 feet per second slower than with S365. With S355, you could probably start off with 33 grains and work up carefully from there. If you seat the bullet deeper in the case than 2.754 inchesm, the pressure would increase quickly and require a lighter starting load.
