Bullet tumbling

[JBS]

Slug your bore to find out what it is. Some of those old bores will go .318 In that case you are limited to cast bullets of that size or .002 over.

Wolf gold 174 gr ammo is actually Prvi Partizan ammo made in Serbia.

Here is your problem you are shooting a boat tail bullet and your Enfield doesn't like shooting them, you need to try a flat base bullet.

Wolf Gold and Prvi Partizan ammo below.



Standard British military ammunition for the Enfield was Mk.7 flat base ammo.



You are shooting the equivalent of Mk.8z boat tail machine gun ammunition.

Try some 180 grain Remington hunting ammo with a flat base bullet, if the bullet still hits sideways or keyholes you then have a worn barrel problem.

NOTE: When a flat base bullet is fired the kick in the seat of the pants makes the base of the bullet expand and fill the bore. A boat tail bullet when fired does not expand to fill the bore and fails to stabilize properly and keyholes or hits the target sideways.

The Rebated boat tail bullet below is like the British Mk.8z ammunition.
