My sawn off shotgun turned out to be 16g, not 12, as a result I need a new slug mould.
I've been using the 12g Svarog Match slugs through a rifled barrel to good effect out to 50m, but this is more just for close range defence shooting against fruit so I was wondering if the ball rounds would work ok to about 25m?
It's gonna go through 18" of smooth, unchoked barrel and Moment Of Watermelon will be fine
