Either way, the true test is does this data repeat itself.

44.1 = 3053, 3012, 3040, 3026, 3047

44.3 = 3033, 3044, 3060, 3060, 3057

44.5 = 3023, 3012, 3027, 3031, 3046

44.7 = 3094, 3060, 3070, 3081, 3079

Would any of you recommend taking it down to tenth grain increments from say 44.1 to 44.6 and maybe do 3 loads at .010 off and 3 at .030 off at each tenth grain increment?
what tool are you using to seat your pimers?
how are you sizing your cases? neck only? if neck only what tool?

personally before i went any farther changing anything id find the reason your getting such high ES's...if you dont get the extreme spread numbers under control its never going to group well at longer distences...if you have some other primers thats where id start...im playing with the FED210M's and am getting eratic spreads.
