Lite Barrel Shot Question (Old School 1100 and A5 "Lead Only")

[Spurs]

Question for the masses regarding a Rem 1100 20 and Browning A5 20:

Both guns have a "Lead Only Barrel" that is the manufactured Full choke.  Also, both are 2-3/4" receivers.

Has anyone produced a custom 2-3/4" load with a Full Choke that can put good numbers on paper?

A friend of mine has an old 1100 20ga 2 3/4 with a 30" barrel uses nothing but Remington Express Extra Long-Range Shotshells. He is a Very Good turkey hunter with lots of experience.
