    Does any one know if the headspace gauges for 338 RUM use the same dimensions as for the 300 RUM. A friend has the 338 Gauges over here in the UK and I wondered if they would double for the .300 RUM so saving the need to purchase further gauges for a potential 300WM conversion. By being able to use the same go - no-go gauges will shave around $150 US of the total price of converting my sendero, just need the reamer?

    Nope, the 338 RUM is a bit shorter than the 300RUM around 0.1"

    I am pretty sure the 7 and 300 RUM will interchange....and that the 338 is shorter.

    A "GO" gauge is all you need bud and they can be bought from Pacific Tool and Gauge for $29.00 bucks. If you don't have the reamer yet, this is also the perfect place to get that too.

    Thanks guys, it was worth checking any way, looks like an order to pacific is required.
