OK, early this summer I finally "inherited" a long promised nice custom Mauser in 358 Norma Mag from my brother in law whose eye sight has kept him from shooting for years. I primarily bow hunt (and a little handgun) so I haven't played with it but decided I want to get back into rifle hunting & maybe catch up with a fall blackie.
Finally took it out last night to clean it & there appears to be a spot of corrosion internally on one side of the barrel. Enough that you can see it as a dark matte toned spot, probably 10" forward of the chamber. Maybe an inch long & covering a third of the circumfrence of the barrel.
I put Birchwood casey gel borescrubber in & let it sit over night & then scrubbed it this morning & the spot is still evident. I'm not thru as patches still come out dirty, but I don't think bore cleaner is going to remove this spot. Pretty sure it's corrosion. Rest of the barrel appears fine.
Where do I go from here in dealing with the spot?
It came with 6 loaded rounds & I'm getting ready to order dies, brass, & bullets.
I've always wanted a gun in this caliber, but don't want to waste my money if it will never shoot.
Do I shoot the 6 handloads that came with it & see how they do?
