300RSAUM to WSM rechamber, gun has slight case bulge?

[jj302]

I have a Remington 700 Police LTR that was 300 RSAUM, but it has been rechambered in 300 WSM
The cases show a slight sign of bulge. Is this the chamber or maybe a headspace issue?
I have seen discussions stating that this isnt "that bad" and the brass should be fine to reload?
I am thinking of selling the rifle and would like to accurately disclose this issue. How much should this affect my asking price?
thanks

My 300 WSM chamber does the same. I run my loads on the hot side. I just resize and reload. Haven't had a problem. I push a 208 Berger at 3030 fps

My 300 wsm doesn't do that.

If that was for sale I would offer you what it's worth minus the cost of a rebarrel if you told me of the issue unless it looks worse in photos than in person. Some hunter may give you your asking price.

Looks like about .0085
