Looking for a Ruger No. 1 tropical in 416 Rigby. It does not need to be in that good of shape, it's going to find a new life as an ELR rig in 300 Lapua or more likely a 30-416.
I owned a 416 Rigby No. 1 for a while. I believe all No. 1 actions are identical except for the extractor. So if you are rebarreling any No. 1 will work, you will just need to buy the 416 extractor.
