No problem gentlemen. Guess I got a bit of egg on my face for the assumption and not bothering to look the actual load number up first to see what it was. I do not have any personal experience with that particular load.

I have purchased and used a number of flats of the Kemen 3 & 1/4dr. 36gr. 7.5 flyer loads and Rio 24Gr. 12ga. bunker loads and both are good pattering high quality rounds.

Sounds like the ammo you are inquiring about is designed for the Brit 'muffler guns' that are used for skeet at some urban area clubs. Will be interested in your findings on its pressure levels.
