Well, in my case, seeing the 1900fps & trajectory figures, I just had to see if I could get some extra range out of the smooth bore.
Dropped the $5+ per 5 shells & grabbed an screw-in rifled choke - prolly another $40. Forgot to mention that these were fired through that rifled choke.
Didn't matter. They were tumbling by 25 yds.
Gun rag article I saw on the Wins said something about 3" groups at 100+ yds, flat trajectory, yada - what's not to like? But this out of a fully rifled barrel. Like I said, had to try it with that screw-in.
Tried to turn my smooth bore into something it isn't - a rifle.
Read a bunch more here in gool ol' TFL - actually researched the archives (do I get a prize?
) & tried some Brennekes.
Haven't looked back.
(BTW, anybody want to buy a screw-in rifled choke tube?
)
