The Magnum Target is the same outside diameter as a regular long action but there are some differences. Aside from the bolt lugs being thicker front to back (9/16" vs 1/2"), the ejection port is much more enclosed to make the top more rigid. They also undergo a different heat treatment process to make them harder/stronger than a standard action. It's still marginal for the 338 Lapua according to some smiths on here, but I haven't had any trouble out of mine yet. For a 300 PRC though you wouldn't have any concern at all since it's a smaller diameter case, it won't have near the amount of thrust that a Lapua case has, which is the cause for lug setback concern on these actions.
Thanks for your input - I ordered a small shank McGowen barrel last night so this project has legs now. :)
