I find factory 20 G shells like the AA or STS recoil too much in my Trojan 20 G. Safe but not pleasant to shoot. For high volume clays shooting and occasional game Quail and Chukkas here are my loads.
Win AA hull Win 209 primer Claybuster 1075 – 20 Wad 12.5 grains Intl Clays ¾ oz shot. Fold Crimp. Winchester AA’s are a bit shorter than Remington hulls, I shoot them without trimming in the 2 5/8 inch chamber. It does not cause any problems. Looking at a fired hull no evidence it’s coming in contact with the end of the chamber
Remington Hulls like the STS are a bit longer and show the end of the chamber on a fired hull, so trim them then roll crimp. It’s also my spreader load, different hull and crimp helps keep them separated
Remington STS trimmed to 2 5/8 inch Win 209 Primer. Claybuster 1075-20 wad 12.5 grains Intl Clays. 11/16 oz shot with a Polywad disk spreader insert on top of the shot. Dropping 1/16 oz shot volume makes room for the Polywad which also acts as the over shot wad. Then roll crimped,
I am about out of Intl Clays will switch to a jug if 20/28 when it's gone. Will pattern and crono when switching
