Just did a search and got two answers. One said, found on here and other sites, that it will fit in the .473? bolt face, but another place said that lapua brass will not fit due to it actually measuring .480. Can anyone clarify this? Part of the reason to go with this cartridge is the lapua brass. Thanks
Whatever the correct answer is, you are anyway going to need a .473 bolt head to begin with, then you could directly test how your sample works with your brass. If it is too tight (everything has a "tolerance"), then the ejector and extractor would have to be removed and the face opened up a few thousandths. It doesn't sound like a big issue. The face if corrected would be done prior to head spacing...
I've had two 6.5 Swedes built on Mauser '98 actions, one commercial, one military. Neither required bolt face mods. Both function very well. I use Lapua brass exclusively. IMO, the folks who say mods to the bolt face or extractor are required for the Swede are engaging in desktop troubleshooting.
If there was ever going to be a problem with this, the problem would manifest itself in a controlled feed action. It hasn't done so in either of mine. If you are using a push feed action, I would expect a push feed to be much less susceptible to any problems related to a case rim that is .007" oversized. If you are using a push feed action, try measuring your bolt face diameter. I bet it is quite a bit bigger than .473".
