So I've been working up loads shooting 5 shot groups at 200 paces with my .223. I've got pet loads now for four different bullets that all seem to have the same pattern of 3-4 shots in a nice 0.5-1" group with one shot 1-1.5" away from the main group.
Always got the flier. A shot I know is perfect could be the one that's off. I'm not a professional marksman but when I'm off by that far I know it. Used all the tools and components I know of to change variables except a case neck turner and primer hole uniformer which I haven't bought yet. Case length, bullet weight, powder weight, trimm length, are being measured and uniform for each round.
COAL seems to be a common suggestion but moving it from touching in increments back to .02 off hasn't done it. There doesn't seem to be much measurable difference.
What would you look at next?
Edit: Should add I've burned through almost three pounds of powder trying different variables so it's been a concerted effort so far.
