1900's action sleeved and proved to 3 tons 1 1/8 oz in the '50's. Six pound 12 bore York House, London Boxlock. Everything is tight and looks good. 3/4 or 7/8 oz loads for skeet and 1 oz loads for birds. I purchased the gun from Hill Rod and Gun quite a few years ago and shot less than a box or two of 1 oz loads at 7200 psi. I would like to start shooting a couple of rounds of skeet a week and wondered how the gun would hold up to 4-5 hundred rounds per year.
