Headspace and accuracy

[DHuffman]

Webster,

Fair enough, I get that. But I'm just applying the eyeball test here. To me, a "flyer" is an obvious outlier, like 4 holes all touching, and one hole 3/4" out of the group. Or, more like 3 or 4 nice groups with all nearly touching, and a fifth group with 4 in a small cluster and one flier. There needs to be a suggestion of precision, with obvious random spoilers. These groups, without any commentary at all to suggest otherwise, just look like every 1.5-in group I ever shot.

Also, almost by definition, I don't think one can justify claiming 2 flyers in only a 5-shot group. A statistical analysis won't support two of the five as being "outliers".

I agree, without knowing the back story and what the rifle/shooter/round did consistently before it just looks like an out of tune load to me. Powder charge, seating depth or both.

All the so called flyers are to the right and vertical stringing. I agree they don't look like flyers. They follow a pattern. Wouldn't flyers be scattered around the point of aim? There is a difference between a flyer and pulling one out. Out of tune, wind or bench techniques? The OP still has not described the rifle. For most us shooters without great bench skills there is a tendency to pull the last shot or two out of the group by not having the patience to maintain concentration. Was there a pattern to which ones were out, always the last shots in the group?
