Help me guys. I got a bullberry SS 13.5 inch barrel on the way from Eds Contenders in 17 Mach IV. Does anyone have any reloading data they want to share. Got some from The Reload Bench for 25 grainers. Found limited load data for 30 grain bullets and none for 20grain. Any experience with this caliber out of shorter pistol barrels. Any help appreciated Ed

Thanks: Appreciate the info, and gives me a broader range for starting Ed
