Can I use slugs in my Weatherby shotgun?

Weatherby recommends slugs only be fired using a non-ported cylinder choke. Smooth bore barrels with choke tubes should have “Cylinder Choke” tubes installed when using Foster or Brenneke style rifled slugs. A “Cylinder Choke” will provide the best accuracy. Any choke with constriction of .020″ or more can result in damage to the barrel. Our “Improved Choke” tubes have a constriction of .013″ and therefore may be used with rifled slugs; however, accuracy may be compromised.

At no time should you shoot without a choke tube installed as this may cause damage to the choke tube threads in the barrel.
