28 ga Repro

I found a chart online by googling -choke constriction in shotgun gauges that appeared on this forum. It went from 12 to 410 and as the bore got smaller so did the amount of constriction needed to get a particular choke designation. For instance .045 for full in 12 but only .017 for 410
It may be that .045 in a 28 is doing just the opposite of what one would think.
The so called turkey chokes i have tested in some guns shoot a weak mod. pattern
Each is individual to the specific gun and load.

Sound to me the issue is not ballistic but pellet count on target.

: the study of the processes within a firearm as it is fired.

Yes Bob pellet count, pressure, velocity and choke constriction are all part of the equation. As I said before, this is my experience and what works for me. Your mileage may vary.

I'm planning on having a 28ga. side event on the Baby Whoop this year at Hausmann's. Let's bring some 28's to have fun with. The proof is in the pudding.

Put it on paper at 30 yards with your hunting load and see if you get a killing pattern. If so, forget about the rest. If not, try a different shot size/load. JMHO.

I have a 28 gauge Repro 2 barrel set. Bird hunting I can't hit anything moving or stationary (slight exaggeration but not far off) with the 26" IC/Mod barrel, but I hit almost everything with the 28" M/F. 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.

Put two shots on my pattern plate, for upland gun I am happy with these.

Both Rio 3/4 oz number 8 shot. That is a 30” circle on plate.

Tom brings up an important observation. He hits (or kills) more birds with his tight choked 28 than he does with the open barrels. 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.

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?

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