I am wanting to get a bore riding round ball mold, but I do not know how much oversize I can go with it.
The bore/groove diameter on my Hastings Wadlock barrel is .728/.732
I have several hundred pounds of new magnum #8 lead shot that will be used for these particular round balls.
I just need to know how much oversize I can go, to hopefully achieve the best possible accuracy potential from these round balls.
Thoughts and or ideas?
Is there any place I can get just a couple of oversize round balls to try out, that are in different diameters?
