I bought a Webly 728 from Bill Jaques in 1980. It was the same gun I had drooled over a dozen years earlier in the H&R catalog. It was $700 in that catalog which also listed a Greener Harpoon Gun cased, identical to the one used in the first JAWS movie. It was chocked 1/4 and 3/4 which I believe equates to I/C and I/M. It only had (has, it is in my safe) 25" barrels. It got me started reloading and I killed hundreds of doves UNTIL I got to reading AND BELIEVING that I needed longer barrels. Still have the 28" straight grip Red Label I bought to fix my new "issue" but it badly needs two triggers.. Bought one of the Parker Repros at close out with 28" tubes, double triggers, English stock and splinter. Had it restocked with French walnut then sent it to Mike Orlean for long forcing cones and chokes opened to I/C I/M. Perfect dove gun? I wish!! The best choke, like the best bass bait, is the one you have confidence in. (Because that is the one you will be fishing/shooting with!
