What do you consider max range in the field for slugs?
The Tactical/low recoil slugs are moving slower so they will drop faster and have much less energy at any given range vs standard slug.
BTW Specs for Shotgun ammo is usually based on 30" barrel which is almost a foot longer than my slug gun's barrel. I expect actual velocity in a slug gun is much lower than what they claim in their listings of the ammo.
