Lloyd, a bolt face on Bats and Bordens are .480 to start with..... jimI campaigned a 6.5x55 GWI for several years using Panda actions. Kelbly's opened up the boltface to .478 to accommodate the Lapua Swede brass. Winchester rim diameter is .473 but didn't hold up well to the pressures I was running. The bolt that is .005 larger still handles other cartridges with the standard .473 diameter.
I hope this helps,
Lloyd
