I have been shooting 3/4oz 20ga loads for desert quail for years. Loaded with #7 shot they seem to be a better load than the same shot in 7/8oz. Which improvement I think may be a result of a shorter shot string and somewhat higher velocity (I just used the formula for regular 7/8oz loads but shorted the lead to 3/4oz along with the minimum powder load. Less recoil and better results for less money too. Put enough rice crispys under the shot to fill the cup when I started this but now just add one cardboard filler instead.

Funny how many people find the perfect 28 load works well in a 20 as well. I started loading them for skeet a decade ago. It was mostly a matter of economics. 28 empties have always been worth more than 12 or 20's and often hard to come across. I came into a very large number of 20 hulls just when my last two sons were getting into skeet and found a 3/4 ounce was perfect for their needs. They have filled a need and I have zero complaint about them. If you do your part they will break birds just as well as any 20 or 28 load.

Ah; The old bug-a-boo of shot string rears its ugly head again. realising that most all shells used today have some form of shot collar the following will ignore that. 3/4 oz of shot in a nominal .550" 28 gauge bore will have a column length of about .910".
3/4 oz in a nominal .615" 20 gauge bore has column length of about .730" while 7/8 oz would stretch out to about .850".
To the best of my knowledge it has never been proven that this has much (if any) bearing on the actual length of the shot string in the air.
i believe you can likely rule out a shorter shot string as being the basis of your Improved shooting.
In fact I can think of no ballistic reason how reducing the shot load by 15% can result ion a more effective load.
My best guess is that due to the lighter recoil you are just "Shooting it Better".
