I have 3 HEs at present. I would use it in any of them but like Stan I prefer the 1 3/8 oz loads. Bismuth 2 3/4"- #4 -1 3/8oz are my favorites. This is as close as one can get with store bought ammo to the non toxic version of the load that made the HE famous. I see no point in carrying a 9 lb gun to launch relatively light payloads.
