I suspect that once the current batch of olde guys are gone on, the now small batch of RN users will go with them.

I use 180gr RNs in a reciever sighted 760 30-06 and 175gr RNs in a Ruger #1A 275Rigby. They won't leave me undergunned in any hunting I will be doing in this part of the world.

Someone mentioned that heavy-for-caliber RNs are the poor man's Partition. This is spot on.
