I have never seen a 25-06 that was as bad as the one that you describe.
My mistake,three problem rifles on your part.
But I will repeat
I have never seen a 25-06 that was as bad as the one that you describe.
I have only fired four 25-06s myself,and while the others were not as accurate with every load tested as the t-3,all four would do sub MOA with their favorite load.And none were any more fussy than any other chambering that I have loaded for.
