[QUOTE="ol mike, post: 158551, member: 4683"] I had the same problem weekend before last. My 22-250 & 25-06 both had hard bolt thrust and cratered primers. The 22 load is 41.3gr of h-380 -55gr sierra blzkg. 25-06 max load w/h-4831 w/a 85gr n-bt. Both guns were off by a good bit on the drop chart.And the 25-06 was grouping 1.5 to 1.7" not its usual .5-.6". By the way it was 96* and high noon -the gun barrels were hotter than hell from the sun alone. Also the POI was off on both rifles. Also shot my cz 221 fb -as usual shot like a champ !Max load- AA 1680 ball powder w/a 40 gr n-bt !!!? [/QUOTE]
