I'm thinking Paul's remarks are spot on about the metering issue.
To Stan's question; the lightest loads Hogdon lists using 800X is 32 grams of lead shot in the 12ga. w/lower pressure recipes. I'm thinking that is because it is not well suited to lighter loads from a ballistic efficiency perspective in that gauge, but in truth, the remark was simply a reminder that it won't be long before the various bird seasons open.
Shoot high flying birds in following winds where the shots can be extreme [over an honest 40 yards; that's 80(!) by the inexperienced &/or poor judges of distance] and 32 grams of #7.5' makes a good dove load. Used to shoot dove out in W. TX w/a former Federal Ammo rep.; he had ten cases, not flats, cases of Federal 36 gram paper flyer loads rat-holed for that kind of dove shooting and he used them to good advantage.
Personally, I've found 25 grams of #7's from a 20ga. the best all 'round dove medicine, but they are not low pressure rounds.
