Randy, the amount of constriction doesn't mean much as far as the original configuration goes. The bore diameter could have been changed over the years. What is the bore diameter of your tightly choked gun?

I think it's interesting and good to know what a gun's choke constriction is but my determination for how tight a gun shoots comes from pattern testing, a 30" circle at 40 yards. The amount of constriction gives a good idea what a gun should do but I have been surprised by some of my results on a pattern board. Examples; Remington 1900 12ga, .014 and .024 patterned 72% and 86%. Lefever F grade 10ga, .003 and .018, patterned 53% and 85%.

Agreed and I get that. Having said that I have measured both bores at .735 on this gun.

to the original Parker question, for me it's .039 in both in a 12ga 3 frame 32" V grade -

anything I have that's tighter than .045 isn't a 12ga Parker

Me to Rick as I have a gun with .039 in both barrels.

I have a 1912 vintage VHE with the left barrel choke constriction of .049. Both barrels measure .732. I'm pretty sure this is an original gun, and it matches the letter. I've not patterned it, but I can tell you it reaches out with that left barrel and will kill a pheasant stone dead at 45+ yards (and will miss them entirely at 20 yards when I'm not on them!).

i have not measured my lc smith long range gun but it will pattern 92 percent out of the left barrel and 85 percent out of the right barrel...thats at 40 yards 30 inch circle... i remember on here that a few people had parker guns with over 50 thousands choke...charlie

This 30" gun has a bore of .730, so unaltered.

My BHE live bird gun is .049 in both barrels which are 30 inches.

Oh my. I would love to have chokes such as those in a gun some day just to play with. :eek:
