I'm no expert on the history either but I believe its not that uncommon for a barrel and action SN to be slightly off in the transition period. and ya its a super grade. There are several "X"s stamped under the barrel so maybe a factory replacement? I dunno. I know an X on the SN means a duplicate SN. IT shoots pretty tight groups with old 220gr silvertips but about 4-5 inches above aim point. Im gonna have to find a tiny screwdriver to lower the rear sight further. I still havent made my mind up on drilling the rear bridge. No to the 350G&H! but they so seem cool. If it gets rechambered it would probably be to 334 OKH

Xausa - no i havent tried that product. It seems to shoot good groups I just didnt know if the bore cam images were anything to be concerned about.

Also, sorry the pics are so huge. I dont know why they posted that way.
