H&R single shot full choke

[stringtalker]

Does anybody shoot a 20 gauge single shot with a factory full choke barrel, no choke tube. Is so what kind of patterns do you get with federal heavyweight #7's or heavy13's?

I have one with a primos tightwad. it is great. I can't give you numbers right off but I'll be patterning soon. I shoot hevi #6 through it and have killed one stone dead at 40
