Ya cant linger on a buy like that!, but I gotta wonder how that is going to hurt you without a good recoil pad buttstock?
'Course you can always swap that speedfeed for one.........
I just popped my old 12 c/w the 'Buck' barrel since the snow on the range is right to see POI without setting targets. Std Federal and Win. Foster 1oz. slugs @1600ish go right where its looking at 40-50yd. (plenty good for deer here in WI). Yours should do as well.
But it is a visious kicking beast!
