Thanks men,When I can get back to the testing it will more than likely be the 180 gr. gas checked for starters.
Probably do a 5 shot sting, But due to fear of baffle strikes after a couple fired minus the can first to avoid keyholing
In other words, If I see key-holes the can's not going on there until I've worked up enough for a nice round hole in the target.
I don't know if these are still around, But at one time Winchester had put out a few sub-sonic jacketed 185 grain rounds
Friend of mine had gotten a box from the rep, I pulled 1 apart and weighed the donut shaped powder.
I want to say 10.8 grains of possibly bullseye powder?
Any other donut powder out there besides bullseye?
