6.5x55 in a .473" bolt?

I 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

I ran Winchester Brass in my Barnard Action work well .
Check the Specs on Winchester Brass OD of Rim is smaller than Lapua Norma etc.

When Remington Chambered some 6.5x55 years back those bolts were opened .
Good Luck
