JamesD,
I use a standard 700mm slug liner at 948 fps with a new power plenum. Magnification was somewhere between 30-32 power and I swage my own slugs. Without the phone mounted and proper form it does a little better.
Arch_E,
Thank you sir. I have a feeling it will be almost normal before too much longer with how quickly this sport is evolving.
Yo,
Yeah you gotta take slugs very seriously and I'm pretty fortunate to be able to shoot in all the awesome places that I do. There was actually a herd of elk standing where I set up my bench when I pulled up.
