Shrap and Ed… when I acquired my wby semi auto it gave me fits with reliability. I knew it was a bit dirty from initial inspection but when I stripped it down all the way it was the filthiest 22 I had ever seen.
I must have sprayed and cleaned 5 lbs of lead and gunk out of the thing. Reassembled and it runs like a top now
Not implying either one of your rifles is the same but something to consider anyway…
Let us know how yours shoots Ed
