I recently acquired a steyr m95m barreled action on gunbroker. It was listed as an unknown caliber so I caste the chamber and determined that has been nicely rebarreled to 257 roberts complete with bolt head modification. I have restocked the gun however before I go any further with finishing the build I was looking for some input on whether this action would be safe to fire modern 257 roberts +P ammo. Most off the shelf ammo for the bob is of the plus p variety and not many are loading it in the standard loading. Thanks in advance.
