I read something about a rule that was created in the early 1900s that limits gun weight to a maximum of eight pounds. Is that still a rule?
There is no weight rule enforced today in flyer shooting, Mike. There are a few rules for the guns and ammo. Main thing is that ammunition is limited to shot size no larger than 7 1/2, and a max payload of 1 1/4 oz. Seems to be sort of split between 7 1/2s and 8s, with many shooters using 8s in the first barrel and 7 1/2s in the second, particularly at the 22 yard line. Some go to two loads of 7 1/2s after running a couple of rings straight and having to move back. There have been a few very successful pigeon shooters that would even use 9s on the first shot. Plated shot is common, in the belief (or, with the proof) that it improves patterns. As far as weight goes, IMO there must be a balance between having enough weight to handle the 1 1/4 oz. loads and being able to get off a quick second shot, and how quick the gun moves to the bird for you. I've never seen a highly successful flyer shooter that used a straight gripped buttstock. Not saying there aren't any, I am just not aware of them. Pistol grips help handle recoil much better for most people, so that the bird is acquired quickly for the second shot, which is crucial.
No rules on chokes, action types, barrel length, etc.
