Bowling Pin Shoot

[Ken]

Is there any rules with what round you use as long as it's not over 44mag?
Can I shot these bullets in my 10mm in the bowling pin match...?

9mm brass swaged into 40/10mm bullets.



180gr

OK, I give up. Why?? Is that a thing now? What advantage or other gain is made by doing that? Just askin'. Pretty much you can shoot what you want.

I should be there tonight.
