I have a Sako 75 Mark V actioned Finnlight chambered in 300 wsm. Not sure if I will rebarrel it but if I do can I go to a 300 RUM or 338 Edge with the magazine or would I need to go to a floorplate? I would prefer the magazine. I haven't even shot it yet so it may stay a 300 WSM just thinking out loud.
Thanks,
Jeremia
