50 Yard 2 3/4" Non-Tox Load?

[Big Friend Ten (BFT)]

Soft shot compresses providing some "give" to the expanding gas.

Hard shot does not yield to the pressure. It provides more resistance causing pressure to rise faster and higher.

Picture a wad stuck in your barrel. Shoot and blow up the barrel because the extra wad provides more resistance to the expanding gas.

I dunno. With today's shotcups, I wonder how much distortion actually occurs. How out of round is reclaimed shot?
