Just bought a 25-06 interarms on GB and took it to the range today and it key holed every shot. Is there any solution other than rebarreling?
thanks for your input

why chase the game when the bullet can get em from here?....
Got Balistics?
Please put me in the know. How and why would the crowning cause the keyholeing?
If the crown is damaged and therefore not true, the bullet's path can be dramatically distorted as it exits the barrel.This damage can be from an impact, or repeated cleaning from the muzzle end. That is why it is recommended to clean from the breech if possible, or at least use a bore guide if needed.

Men, like bullets, go farthest when they are smoothest.

Yes, have the barrel crown recut. If thats what it is, and not the twist rate vs. bullet weight like TWalker suggested.
quote:,..look to see how much rifling is left in the bore.
Throat erosion and bore erosion can contibute to keyholing too.
Things you/we need to know before diagnosing:
Twist rate
Bullet weight
Throat & bore erosion
Freebore (distance from bullet to rifleing)
Damage to the muzzle crown
JustC, Did I miss anything else?
