No need to justify staying with the 260. If you like that chambering, then stay with it.
If you dont like the stock that is on it, get an aftermarket. You can always shorten the LOP.
Since you are having problems "getting down" on the scope, some higher scope rings might be in order.
If you do not care for the Matte finish on your rifle, you can spend some time on the polishing wheel and put a high polish on the metal with rubbing and then polishing compound. This takes a lot of time and one of the biggest reasons that having a rifle hot tank blued is expensive. If you do the polishing, then a smith will tank if for you for a reasonable amount.
Remember, you can put as little or as much as you like into getting the rifle the way you want it.
No such thing as a stupid question. What is stupid is not asking it.
