If you are chasing Kansas ditch parrots, the proper load is #5s and tight chokes. If they flush close, give them a tic or 2. RST Lite roll crimped 1 1/16 oz, but I don't see it on the website @ RST. If you can stand the pressure, Kent's Upland with the Diamond shot works extremely well. I have not found a better type shot.

Kind Regards,
