I'm in the process of getting the parts together to have a 7MM PRC build, the barrel is on the way. I have a Stiller Predator Action I bought many years ago with a .595 bolt face for a .338 Lapua. I need a long action magnum bolt for this build, and I'm looking about $400 for a new bolt. I know a ring can be installed to make the bolt face smaller, not sure on the cost and something tells me it's probably not the best way to go. I can probably sell my bolt to lower the cost, which might end up being a hassle. Are there any options I might be missing? I have Remington 700 magnum long actions which can be used for the build instead of the Stiller Action, but I didn't want to go that route. Thanks.
