A person shooting at game and missing it with something going over 2000fps would be endangering people/property. I do not want to see muzzleloaders restricked in these areas yet I want to keep using a rifle like my encore.
That is a precarious position-- Encores have had published loads over 2300 fps for years, now, and slug guns long ago eclipsed 2100 fps. Difficult to draw an easy distinction.
