A friend of mine had a custom .243 build by a well known rifle builder and he recommended not going for the 55 grn and using a 70 grn or there abouts equally dead foxes but a longer barrel life.
Not bad from the man who would probably get the job of putting a new barrel on.

Interesting reading boys.
I might be looking for a dedicated foxing rifle shortly. It'll be a Howa, but i'm stuck between .243 & .22-250....
