Thank You very much Mr Keenan, and Uncle Nick. The cutout does start at 1 o clock down to 5 o clock where it ramps up towards 6 o clock, and there is a small cutout, where it looks like some pin in the bolt interacts with the breech, at 6 o clock.
Right around 5 o clock, it has a pit or two in it, but not very deep. Will this cause problems feeding? Do I need a new barrel? I might have over-exaggerated abit, I apologize, but it is a big purchase for me. I paid $1000 for this rifle with no guarantee, from the shop.
