Home Forums Hunting & Shooting Express Rifles and Big Bores Only 9.3x74r inserts in sxs 12 gauge

Here is a typical muzzle end with the four adjustment screws.




The Keppeller insert in the drilling shown has the screws around the front on the sides, not at the end. It means the insert needs removal for each adjustment. I prefer the first type, as with the Kreighoff insert.
