About three or four years ago my dad bought a used .223 barrel for his Blaser R93 bolt action rifle. The gun had originally been a .30-06 but it had a very unpleasant kick.
Anyways, from the get-go we seemed to have problems with the accuracy of the thing. It didn't like the 69gr Remington match ammo, neither did it like the 55gr Norma Oryx we tried. The 40gr Vmax finally delivered acceptable accuracy.
I shot a fox at 50yds and a crow at 150yds with it but when shooting paper it always shoots 2 MOA (with fliers) or worse. I'd say out of 5 shots 3 or 4 are fine, but the rest are fliers.
Since I don't think there's a free floating issue - a sheet of paper slides between stock and barrel pretty well - and there is no visible damage to the crown I suspect a shot out bore.
Has anyone here got input on this issue?
Boomer, I hate to ask you this but did you change out the bolt head to a mini when you removed the 30-06 barrel?
