6mm BR. R15 & H380

[muzzleflash]

New to the board with a new 6mm. br. build. I have on hand some 68gr. & 88 gr. Berger's, some H 380 & R15 powder. Will these powder's do the trick out to 300 meter's? Also what would be a good starting point using these component's?? THANK's

I used H-380 a couple of times with the 87 SP & 100 gr spitzer..I was underwhelmed..Stick with what is suggested here...I found using regular primers instead of magnum helped with my light bullet weights 75 gr V-max really improved the groups...in my one in ten twist Hart barrel 6mmbr..mike in ct
