While shooting sporting clays yesterday I ran out of RSTs shells for my 1882 WC Scott hammer gun. I was on the 2nd to last station so I grabbed some low recoil 1oz Herters to finish the round. To my surprise, the Herters kicked way less than the RSTs (quieter too). They also run run about 1/2 the price. So I'm thinking about using them regularly but was wondering about the PSI on these shells... The 1oz, low-recoil, 1060 fps shells. After shooting them, I would guess them to be very low. But how suitable are they for vintage guns?

The gun I was shooting is a pretty stout piece. .044 thickness on 30" damascus barrels, 7 1/2 lbs, dolls head ext, etc. Chambers appear to have been opened to 2 3/4". The gun is perfect for sporting clays.

Any opinions and insight would be much appreciated.
