- - 28 ga Repro (https://parkerguns.org/forums/showthread.php?t=35124)

The chart i mention is here in the FAQ section on the home page , it is #12.

Tom, the 28 gauge full choke Repro constrictions are off the chart. Parker Brothers full choke in 28 gauge is .020. Whether the "off the chart" full choke in a 28 gauge Repro is effective depends on how it looks on the pattern board. I will shoot some patterns when I get time and report back.

Obviously, he is hitting birds with the open barrels, but doesn't put them in the bag. He is crippling the birds he is hitting with the open barrels. Gives a little more credibility to Daryl's post. Tight chokes are the only choice for serious bird hunting with a 28, except for quail, woodcock, and sometimes, grouse. What do you open choke guys do with a grouse when you miss with the first barrel? Luckily, Tom learned from experience, as have Daryl and I. 28 gauge Repros with IC and MOD are a better choice for general bird hunting than the Quail 1 and Quail 2. MOD and FULL may be an even better choice.

I just measured my 28 Reproduction 28" and the right barrel is .033 and the left barrel is .044, this is way off the charts for a MOD / FULL choke barrel. I haven't patterned it mainly because I shoot the 26' IC / MOD barrel so well.

.044"? Wow! And I thought .044" was tight in my 12 gauge Fox Sterly

I can not even get the Galazan Dial gauge to go into the left barrel its so tight. I had to measure the bore diameter from the chamber end and mic the muzzle end.

Brett and others, what are the choke constrictions of your 28ga. 26" IC/M barrels?

The reason I'm asking is that I'm seeing some variations in 28ga. Repros IC/M and M/F choke constrictions, but the Q1/Q2 chokes are very consistantly within a thousandth or two of .004/.007.

Wow. That Mod is actually full its seems.

Thank you Brett.

Is it the my physical mechanics of using a longer length barrel or the tighter chokes that give me better results with the 28" M/F barrel? The down side of the 28" M/F is I obliterate close birds with the Mod barrel and thinking of having it opened to IC or Light Mod.

Wilmurt, it would be interesting to see what your Repro 28ga. IC/M set of barrels mike out at. Would you please measure them and report back?

With the small sampling from this thread we are seeing some significant differences in the constrictions that varies from gun to gun with the 28ga. Repro's IC/M and M/F chokes.

So far the IC/M set of barrels the IC varies from .004 - .011 and the MOD varies from .016 - .023.

With the M/F set of barrels we're seeing even more variation, the MOD constrictions go from .014 - .033 and the FULL constrictions go from .034 - .045.

Any one have a theory on why there's so much variation in the above sampling?
