I've fired a grand total of 6 target loads out of mine since it arrived last week, so that makes me an expert on the subject, right?
Obviously, they're fine - non issue so far. I'm a little shy about firing slugs, but I suppose I'll get there eventually... Not only are they $2 a round, but I'd think they are the ones to worry about. Hey - if I break my shoulder, the KSG is ambidextrous, right..?
I'll chime in again when my setup is complete and I do a few rounds of trap. With the 20 gauge I've been using, 50 to 75 rounds in a day is no problem for the shoulder, it's the cheek bone which takes the beating. I'm more concerned about having to get so low on the KSG and the rotation from holding it high in my regular stance... We'll see I suppose.
One thing I will say about shooting the KSG is that before the temperature drops, that receiver cover is going to get a blankey - damn that thing is cold on the face.
