Im in the market for a 338. Im thinking the 338 rum. from what ive read its equivilent to the 338 lapua in performance with cheaper brass, and a little slower than the 338-378 but the weatehrby also requires some expensive brass. I have never had a rifle built before but my game plan was to get a action, have it barreled and put a stock of choice on the rig. I have always liked remington 700 actions so thats what I was going for. But weatherby and sako actions seem solid built too. I mainly seem to hear of people building rifles on rem 700 based actions tho is there a reason for this I guess my question is how do I go about getting an action? Maybe Im not looking in the right place, but I never seem to see actions for sale? where does everyone get there actions for a build IF there using factory actions? So is my best game plan to buy a used rifle and just rob the action? Im not agianst custom actions they just seem a little spendy Next question for example lets say i get an action and bolt from a 300win mag. Since this is a LA could it work for a 338 rum? Is the "extractor" on the bolt replaceable? or can it be machined out to fit the 338rum case? or do I just want to look for a 300 or 338 rum action to base my build on? I am open to all suggestions!
