I would think so.  There are dimensional drawings for chamber and brass and they typically play well together.

I am curious who had problems with Lapua brass in a standard chamber.  I have heard of problems with the occasional tight necked custom chamber, but not in a standard one.

I use Lapua brass in my .260 CTR with no problems at all. I highly recommend Lapua brass over any of the other brands I have tried.

Bought 300 lapua .260 cases a couple of months ago with no problems at all.
