Hi, I have been around the chunk and shooting game for a good bit and some of the best 10 shot strings that I have ever heard were just right at 2 1/2 inches. There have been several three shot string shot at friendship that measured under 1 inch, some that have measured under 1/2 inch. There are two classes of chunk gun. Usually a light chunk gun needs to weigh 12 pounds or less. Other than that chunk guns don't have weight or caliber limits. I have range officer the Alvin York for the past 5 years shoot around 10 to 12 matches are private clubs. Every year, and of course do the friendship, thing twice a year where I spend most of my time as a range officer rather than shooting. I read where one of you didn't think too much of getting up and down off the ground anymore. I don't blame you. That's why we came up the table game where were at. The chunk gun. I shoot weighs around 28 pounds. I think my chunk weighs around 12 then of course there is a loading box. The stool what I stand on to load the doggone thing in the spotter. Sometimes I think I need a forklift carry stuff from truck to the range, but it's all a lot of fun. :grin:
