[QUOTE="ak fury, post: 518745, member: 34880"] .338/.378 Mark V Accumark Ziess 4.5X14 Tried up to 114 gr. reloader 25 everywhere from .050" to .070" off the lands. Speed was 3260. OAL was 3.830" @ .070" off the lands. ( this won't go in a factory mag & won't feed)"At least with mine" !!!! ( had to make some changes). Was seeing some pressure signs I didn't care for and dropped back to 113.5 gr. & .070" off (which it likes).Nice groups, well under 1 MOA with today 3" to 4"@ 600yds, some burnishing on head , primers look good,a little tight coming out once in a while, I'm going to 113gr & try that & see what I have for M/V etc. Are you guys having consistent copper fouling @ the end of the barrel with these velocities? My barrel is clean, I mean clean,hours & hours of polishing w/ JB from course to fine over & over etc.????? I can usually get 6 to 8 rounds and then things go south. This thing is a "tack driver" if I could just keep the barrel from fouling with Copper. [/QUOTE]
