They have launchers you can operate yourself.
If you use slugs, be sure to put the right choke on. You don’t want a full choke.
Also, make sure either the barrel or the slug is rifled, but not both. I doubt it’s a rifled barrel, but if it is, you have to use a slug made for a rifled barrel.
It’s smooth, both barrels are. I have been running rifled slugs through the 18.5” barrel. I wish they were cheaper. I love shooting them.
I am going out to the range after lunch. Think I’ll see what I can do out to 50 yards with slugs in the 18.5” then move to the 28” for comparison.
I like the Savage 350 pump for the most part, but it only has a bead sight. I originally bought it just for home protection, or a zombie invasion. But I guess it’s time to see how useful the 28” barrel will be.
Much as I like my other long guns, you can’t get past the brute power of a shotgun for self defense.
