Finally got out to the range to shoot the Armusa 2.5” 7.5 referenced above. My impression…buy as many as you can afford. Amazing shells, deadly out to 45 yards, destroyed clays when I did my part. As compared to RST 1oz 7.5, felt recoil was just very slightly more. Pressure apparently is comparable. As compared to the game bore, much easier on my vintage action. Cut one open and found hard, consistent shot. Amazing value vs. RST and as an added bonus my barrel was very easy to clean with almost no residue. I would wholeheartedly recommend these shells.
