WC and SWC beat it in every conceivable way, except one. Better for target shooting. (With my crap eyes, I appreciate big holes in paper more and more all the time.) Better terminal ballistics.
The only advantage I see to RNL is slightly faster reloading. Much like Hornady's pointy "filled" JHPs.
I've never handloaded RNLs. I've never even contemplated buying RNL bullets to handload.
My impression is: inertia. Maybe the international market that fears effective bullets?
What am I missing here?
