I've had a hard time believing a #9 shot made out of anything has enough energy to kill a bird at 70 yards and I worry about that stuff tearing up my barrel but yall have just about got me wanting to try this stuff out.
What kind of wads and hulls yall using?
I thought that too when I started using it 5 yrs ago, so I decided to use #8 shot and put it in a 3.5" hull and get the speed up to 1250 fps.
It was all a waste of time and money. If had been smart, I would have just used Hal's original 3" load and #9 shot. Not that my loads are no good, they are just overkill.
You used to be able to buy the shot over the phone from a guy in ok, but he went out of business. Hal is the only source I know of now, and he also has many lab-tested recipes. Don't worry about your barrel, just follow the recipe and it will be fine.
