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.

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.

Funny I never checked them before and to my surprise the they are right barrel .008 and left barrel .023.
-Brett

Wow. That Mod is actually full its seems.

Thank you Brett.


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?

28 Gauge Choke Measurements (measurements repeated 4 times)

26" IC/M
1. R-bbl .007” .553” Bore
2. L-bbl .018” .553” Bore

28" M/F
1. R-bbl .020” .553” Bore
2. L-bbl .045” .553” Bore

Have you checked POI with your 26" IC/M set of barrels?

POI was checked and there’s no issue

If the POI is hitting where your aiming, your .007/.018 chokes are, at least in my experience, sufficient and effective at any reasonable distance for a 28ga. with proper loads for the upland bird hunting I do.

If it were me, I would do a quite a bit of target shooting, i.e. skeet, 5-stand and sporting clays before giving up on them.

My issue is not with the 26" IC .007/Mod .018 chokes, but the 28" Mod .020/Full .045 chokes and, yes I've shot about as much clays as possible to figure this out too.

Tom, the above is what you wrote. I've read and re-read it several times, and each time I read it I come away understanding you "can't hit anything moving or stationary (slight exaggeration but not far off) with the IC/Mod barrel, but I hit almost everything with the 28" M/F." (The words in quotations are your words, not mine). I thought it was the IC/Mod set of barrels you couldn't hit anything with, I'm sorry if I misunderstood.

Don't need to be confusing. I still can't hit anything with the 26" IC/M. with the gunsmith's assistance I believe the IC/M barrels are choked correctly and there's no issue with the POI. Also had the gun stock measured and compared to my 20ga. Repro and found the 28ga. stock measurements to be similar to the 20ga. As my father always told me about my shooting ills that "its not the arrow but the Indian".

Since I hit more clays and live birds with the 28" M/F barrel than the 26" IC/M my gunsmith has summized that my shooting technique is different with each barrel. It seems I swing faster and not as smoothly with the shorter barrels than with the 28" barrels. The added weight of the 28" helps my swing too. I am having the 28" M/F barrels opened up to more conventional 28ga. chokes of .013"/.027" than the current chokes of .020"/.045. I'll be keeping the 26" barrels in the case.

Man, I wish I had a set of barrels for you. I am in the opposite camp, I would really like to have a tight choked set of 28" barrels to turkey hunt with. It pains me to hear this....

What’s the ‘I’ stand for
 

28 gauge DHE Parker Repro. Barrels match. Can’t figure out what the stamped ‘I’ is. Anyone?

The "I" stamp meaning has been brought up several times in this forum. Like, Mr. Spencer, had responded previously to you-- no one seems to know. Here's one of those threads where it's been brought up before: http://parkerguns.org/forums/showthread.php?t=5012
