Ah okay yeah I get it.. 204 ruger or one of the 20 cals based off the 221 fireball case sounds like a sweet option to me. I’ve never had a 220 swift. I’m sure they r fun to shoot! I like 223 and 308 for bulk ammo options and for long barrel life compared to some others. Wish i kept my 17 hornet but that things so tiny it’s almost no good for larger dogs. I’d keep 17’s for small critters. If you can’t buy factory ammo that may steer a lot of people away. Some don’t care and love to reload.
