I am looking a recipe for buffered lead shotshell loads. I had a friend I used to shoot with and he used white flour for buffer material. I would like to use a poly or plastic type of buffer but can't find any info. Want to use 4756 with 11/4 oz of #5 or #6 lead shot in a Federal gold metal case or in a Winchester AA case. I have several loading books but can find no buffered loads in them. I shoot trap, money shoots, meat shoots, games. We shoot anywhere from 27 to 50 yards from the trap house if your 3rd or 4th shot on a missed target it's out there 70 80 yards. My friend that shot the buffered loads did very well but has passed on and I never got any info from him.
