Each barrel is an item unto its self. You will just have to pattern it yourself. Anything else is just a guess.
What is the difference?
Thank you Mr. McMillen for the loading info. Can I assume that you load 1 1/8 shot. Been trying some 7/8 and 1 ounce loads, but not breaking targets well; many large piece breaks. On Friday with test some 1 1/8 loads with 20.5 green dot. Hopefully the denser pattern will breaks targets much better.This is the load I used: AA CF hull, 18.5 gr of WST, Win 209 primer, RXP wad, Rem Mag 9's.
I had a Perazzi MX8 skeet gun with enlarged muzzles and vertical slots plus a Rottweil Olympia 72 skeet gun.I would like some input as to your experience for loading 12 gauge Tula Choked Barrels (jug choke), k80 28 inch. I know about the history and that originally ammo was primarily made with felt wads.
However can you recommend what you have found best for skeet shooting this barrel as far as shot weight, type cup wad, and best speed for skeet shooting?
I had a Perazzi MX8 skeet gun with enlarged muzzles and vertical slots plus a Rottweil Olympia 72 skeet gun.
When I first had the Perazzi I was supplied with Rottweil Stern ammunition, one of the most expensive 32 gm high brass skeet shells on the market at the time. There were no plastic wads in the Sterns. After having two (!) bloopers in a shoot-off in Finland for a medal in the Nordic Championships, my friend Ole Riber Rasmussen took pity on me and arranged for Danarms, the Danish manufacturer, to provide me with the same ammunition he used. Danarms shells had plastic wads. From a shooter’s perspective I can’t say I noticed any difference, i.e. between the plastic wadded Danarms and the non-plastic wadded Rottweils, except to say I never had any bloopers with the Danarms!
In 1964 I shot on the same squad as Conny Wirnhier for two days in the English Open Championship which he won. He went on to win the ISSF World Championship in 1965 and 1967 plus the Olympic gold medal in 1972. When I shot with Wirnhier I can remember he used what looked like a fairly crude prototype of the Rottweil Olympia 72. It was similar, but not the same.

I used all kinds of ammunition, i.e. plastic wadded and paper/felt wadded, through my Rottweil Olympia 72. I never noticed any difference from a shooting perspective in either kills or scores. However, I shot my best scores at Olympic skeet with Perazzi and Winchester shotguns made for me with plain old unadulterated true cylinder/true cylinder barrels without any fancy “improvements”.
As an aside, shortly after the Berlin Wall came down the top Soviet Olympic skeet shooters ditched their Tula choked MU-6s or MU-8s and switched to Perazzis! That must tell you something about the so called 'magic' of Tula chokes . Good luck with your reloading.
Yes, 1 1/8 oz load. Never tried a smaller payload.Thank you Mr. McMillen for the loading info. Can I assume that you load 1 1/8 shot. Been trying some 7/8 and 1 ounce loads, but not breaking targets well; many large piece breaks. On Friday with test some 1 1/8 loads with 20.5 green dot.

I would suggest you find someone with a bore gauge, and don't do anything with the choke until you find out the bore and the choke constriction. The choke will be in the last 1/2" in your barrel. Mine was an .004.Thank you very much for your input. Nice to hear from someone that has so much history in world shooting. Also very important for me to hear that plastic wads should work just fine.
If I do not like the way I am breaking targets with these barrel because of the Tula chokes, I most likely will send the barrels to Briley for re-choking. However I am going to try some 1 1/8 loads this weekend and see what happens. I found last week that both barrels had the same POI at 20 yards; namely, 50/50. The patterns looked really good with the cup wads and the wads always hit the target on the side. But I noticed the wads were very darkened with burnt powder. I guess perhaps this is occurring because of blow by in the barrel.
I wish that I had a bore gauge to determine the bore size before the choking. Originally the barrel was marked 18.6 mm. On top of the 18 area is stamped a large 0. I do suspect the barrel diameter is larger than 0.732. Perhaps the larger diameter barrel is causing the blow by.
