Q: I have been told that rifled slugs may burst the barrel of a full-choke shotgun and thus should be used only in cylinder bore guns. Does the same thing hold true for OO Buckshot?

A: Rifled slugs or buckshot will not damage the choke of any good gun. I specify “good gun” because I once saw a cheap South American double bell-mouth both muzzles when rifled slugs were fired through it. Slugs are soft and their thin lands will seal and take the bore without any undue pressure. Fine shot have a jamming effect and develop much more pressure than either buckshot or slugs. I find very little difference in the accuracy of rifled slugs with different chokes. With buckshot, the larger the shot the less choke is required and a very tight choke will usually give a scattered pattern.
