Hi all, I've used their 2 1/2" 12 and 16 loads with a 1oz payload. Darn good shells. I do roll my own now, so I've not used many as of late. I do have a few boxes of their 2 3/4" 1 1/4oz Pheasant loads. Really like these for my more modern guns as well as a couple vintage guns that are chambered for 2 3/4". These loads have a pressure of 7800psi or so. Well within the pressure limits for guns with a service proof of 3 1/4 Tons psi.
