So I finally got to reloading for it 200 ELD X 75 and 76 grains of H1000 Foster Dies and LFCD
3.515 COAL and 2.848 to the Ogive .027 off the lands and bumping the shoulder .003

First day out got her sighted in and happy with 1 Moa groups at 100 yds 1.5 inches high this was Factory Hornady 200 eldx
Cleaned barrel back to spotless
Next day out with the reloads at the 200 yds bench. Ok I shoot 5 times and not even on Paper What? I check scope then brake then the bullets cannot be vaporizing.
6th shot finally Low about 8 inches OK.
Next 20 bug holes and I mean dead center then I try my 76 grains of H1000 1.5 inches high at 200 and more bug holes

1 question is do many barrels take 7 shots to foul up and get back on target I was getting very nervous before #6 showed up LOL
Never had a barrel with 5R rifling

She sure is fun to shoot with the top 4 plugs removed she doesn't move
Scope is Mark 5 HD 5x26 56 Illum TMR

No two barrels are the same. Read threads stating anywhere from 2-10 foulers till on target. Waiting till accuracy fades, then clean Is the norm.
