Mauser C96 Bolt Stop Hole Deformation Question

[milesc2]

I recently purchased a C96 Bolo Mauser SN: 469828, it appears to have been re-blued and re-bored at some point in its long life. It is all matching numbers except the bolt and bolt stop. I have fitted a new safety and re fitted magazine follower (it would not feed the last round). But now I have a question regarding the bolt stop hole. The back edge of the frame is straight as an arrow but the rear face of bolt stop hole has a slight bulge. I wanted to get the forums consensus on the safety of firing this pistol. I think it will most likely be fine as I have been looking at a lot of early Bolo Mauser photos online and most of them seem to have this same bulge. What do you guys think?
Also, I know to never shoot 7.62x25mm and I plan on replacing all springs with new ones from Wolf. But I do not know if I should opt for the 10% stronger springs or not.

Does anyone have any advice?

Thanks in advance!
