30" WOW - they looked as long as my squirrel rifle barrel. 1st thought came to mind.
Still look long in the case.
What a great gun to own - & use.
My London gun 2 1/2", does really well in plastic cases, hard card, 1/2" fiber, 75gr. 1F and 1 1/4oz. 7 1/2's.
An English friend suggested 2 1/2 drams would do even better.
