What do you like to use for small/large Pesting

Well, according to the info on this link you need about 50fpe for a "feral dog".

I'm shootin a AGT Vulcan 3 in 30 caliber well above that. Sub MOA groups at 100 yards. At muzzle it's over 120fpe and at 100 yards it's still over 90fpe. with 60gn slugs. I'm shooting lighter slugs right now, 52gn at 113fpe.

For what you're doing I would still go with heavier slugs for better penetration.

The 1st chrono reading is at muzzle, 2nd is at 100 yards
