I wanted to see and put on paper what a Spred-R disc did through my 28ga. Repro's FULL (.034 constriction) choke at 15 paces and compare that to the same load w/o a Spred-R disc. So I loaded up a few shells with the Spred-R disc on top of the shot. Yes, the disc is a somewhat snug and tight fit in the AA hull, but as Martha Stewart would say "That's a good thing!" I used my standard Sporting Clays load for comparison:
* AA compression formed hull * W209 primer * 12.9gr Universal Clays * CB1075-28 wad * 3/4 oz. #8 magnum shot * 1200 FPS * 10,800 PSI* * It has been estimated that the addition of a Spred-R disc results in less than a 500 PSI increase in pressure. The first pic below is the pattern at 15 paces with the Spred-R disc. It resulted in a 19" pattern spread. The second pic is a same load, but w/o the disc. This load resulted in only a 10" maximum spread at the same 15 paces.

I really like that 10" pattern. By the way, every full choke 28 gauge Repro I have measured measures .039 constriction. Every full choke Meriden Parker 28 gauge I have measured measures .020 constriction. Nothing wrong with either one if the birds are far enough away.

The tightest patterns I've seen on paper were out of my .044 Sterly. I can't imagine. 039 in a 28 gauge. Is it possible that the shot gets deformed enough that it begins to throw fliers which spread the pattern?

Without question! Cramming 1/2 - 5/8 oz through that hole is going to yield a very unpredictable shot column. |

Let's hear from some other full choke 28 gauge Repro owners. Edgar says his are all in the 20s, and everyone I have heard from on the net says .039. OH, me too. The truth is, who cares?

You had me second guessing myself, Bill. I measured a bunch of guns yesterday, mostly 12s and .039 wouldn't shock me on a 12, but I was wondering if I was thinking 28. I looked at some chart I have glued in the top of my barrels tool box, and sure enough, .024 is "Extra Full" in a 28ga.
I'm not saying you haven't measured a bunch of Repros at .039" even though I haven't, which leads me back to my question; what would possess a person to choke a 28 so tightly? And, to your point, Who cares? |

My 28 gauge Repro M/F measured .040/.047. A little tight.
