Parkers and Pressure ?

One ounce loads should be find in your GH. I shoot 1 oz. for trap and 7/8 oz. in skeet with my fluid steel and damascus guns.

Your gun should be fine up to 1 1/4 loads.

Gene .063 at the muzzle means very little and is more a result of how much choke the gun has more than anything else. To determine if a gun is safe to shoot you should have the wall thickness measured a few inches in front of the chambers. To do this correctly you need a wall thickness gage that most good gunsmiths should have.
