While researching bullets for my 25-06 I saw a few in 6.5 that had BC of better than .6 at a weight of 105gn. Back when you'd get Winchester bulk bullets in 60# quantities(3360ea of 125gn JHP .357) we used to swage some with Corbin sizers to .355 with no issues.
But the Corbin page says .006 is max reducing size due to springback and resulting core seperation issues which would leave me with a .258 bullet.
Looking for some insight.
FWIW I found this and wonder how many lawyers would pass out reading it.

Firing over-sized bullets with mild or moderate loads (tested safe in the weapon) is not an issue.
And, when it comes to lead bullets...
I suggest nay-sayers give P.O. Ackley's Handbook for Shooters and Reloaders, Vol. 1 a read. There is an article that discusses this very issue. The climax of that article:
Mr. Ackley had customers asking what to do with generous throats or chambers in .30-06 or 8mm-06 rifles. His solution? Leave the .308" or 8mm barrel on the rifle, but open the chamber to .35 Whelen, and shoot .35 Whelen ammo with lead bullets. When fired, the .358" lead bullet is drawn down to groove/bore diameter, doesn't cause pressure issues, and is quite accurate.
One of the most respected gunsmiths and experimental ballisticians of this century is telling you to fire .35 caliber bullets in a .30 caliber bore.... and people continue to argue over 0.001".
It's standard reloading practice:
Start low, and work up.
