Any ideas as to why I'm getting flyers? They seem to be the same distance from the main group. First pic was shot last a week before the other two. Outside temp maybe 60 deg. Good cross wind.
Same load as above, shot one week later, but temp was 20 deg colder. Barrel never got warmer than luke warm. 6 shots total. First 2 shots, cold bore, were almost touching. 3rd shot was the 1st low flyer.
3 shots but bullet seated into the lands at 3.195" to ogive vs 3.175". Shot a few minutes after picture 2. Barrel never got hot but there was probably a 20 deg swing in barrel temp.
Primers are Fed 215 and seated with a hand seater that has a solid stop.
Once fired brass, 7mm mag bump die set to just touch shoulder and zero bump.
I re set the pan with every adjustment to the powder charge till the scale zeroes. Scale weight is verified with check weights.
I do notice that on occasion a cartridge will measure long from the bullet ogive to case base. I then adjust the press and continue seating till that cartridge measures within .001.
