I dunno...the .22 Creedmoor I am currently having done is being set up for 80gr Amaxes, and its sole mission in life will be coyotes.
This cartridge, of course, will be different. Within the confines of an AR magazine, the 73gr ELD and 70gr RDF will be pretty fun at the speeds this should produce. A slow twist is a handicap on any cartridge, but especially on one like this.
