I have shot about 10 flats so far of the 3/4 oz. 2 1/2" shells in my vintage English guns and they are great. RST are not available in Canada and these are the only reasonable choice for 2 1/2" shells here. The Gamebore field loads are available but at $25.00 a box but I'm not rich enough to burn them up on clays.
I urge everyone to keep purchasing these so that they are not discontinued. Way more effective than the Winchester low recoil, low noise, 26gm in my opinion.
I have no idea what the pressure is but I'm sure it is not very high. It would be hard to generate more than 8ooo psi, even with the fastest powders in a 3/4 oz. 1200 fps 12 ga. load.
I've been shooting the 2 1/2" as well and really like them. However, I believe RST are available through Prophet River. Frieght is a bit steep sending them all the way to Alberta and then back to Ontario but might be a bit better for you, being based in Calgary.
