Handles everything you can throw through it, including 3" Winchester slugs (1750 fps), though it'll kick your arm off your shoulder. Patterns very well too. Slugs for dear, Buckshot for serious dealings, and if Federal ever gets around to making a Birdshot with a Flight Control wad, I imagine it would make a pretty good wing shooter.... I personally use the 9 pellet Federal 00 Buck (Flight Control) as my Sunday-go-to-Meet'n load in it. Given the 320's ghost ring sites and the tight Federal pattern, liability across the Sanctuary is kept to a minimum. You see, the Deacons in my church double as security and this one is also the Bass player. From the stage to the front door is less than 30 yrds. It may not be the Sword of the Spirit, but the Sons of Edom would think twice after feeling it's lightning.
