Had .5 moa left wind dialed for 200 and 1.25 moa left wind for 400.
This is brand new lapua cases and going off the 8 moa comeup needed at 400 my velocity is way down. I might even use this load to fireform some brass at the 200yd but might need to fiddle a bit more powder into it for 400yd its like a shotgun
If you look at the 200 m group it looks very much like the 400 m group! Timing seems slow!
Wilddog Mark Fairbarn once said “ if it doesn’t group ad more powder !” With caution of course. The projectile looks slow !! And is possibly negatively compensating ! Ditch that load !
Speed up timing a bit by jamming and trying oring tunning ! It makes a good load want to shoot and a brilliant load super tune !! It’s also very cheap to do ! Nothing ventured nothing gained !
There is just so much to learn and bad groups could also be shooter error like one flyer from my group in pic above post ! Trick is knowing what’s rubbish and what’s good info ????
Let me know how u go with harmonic oring tuning ?
