does the 338 rcm have any advantages over the 338 win mag? I dont really know much about the 338 rcm other than short video clips i have seen and supposidly you get the same performance from the 338 rcm with a 20 inch barrel that you would with a 338 with a 24 inch barrel. im planning on buying a 338 really soon and i was wondering if maybe the 338 rcm would be a better choice over the win mag. I reload so take that into consideration.
