drsfmd has it right on the money....

1:14 is OK for 45 grain or lighter bullets

1:12 for 52 grain or less (maybe 55 grain)

1:10 for 60 grain or less

1:9 for 69 grain or less

Also.... Wolf ammo is about as cheap as you can get.... not inexpensive - cheap - there's a difference. Try some Black Hills 55 grain FMJ.... relatively inexpensive reloaded Mil brass.... otherwise, Federal "American Eagle" stuff.

If you still have trouble, try slugging your bore.... you may have a bad barrel.
