20 cal cartridge formed from .243 brass ? - 10/16/22
I'm looking to have a 20 caliber rifle barrel assy for my Savage Impulse Predator .243 chambered rifle.
I've been using a turn bolt rifle chambered in 20 practical for my restricted area predator hunting needs in NY state.
I would like to use the Impulse rifle for all of my predator hunting and swap barrel Assy's when needed, but Savage doesn't offer a .223 bolt head for the Impulse yet or maybe never, so I'd like to find a 20 cal cartridge that's based off of the .473 OD rim dia of the .243 that doesn't need to much work to form it or special magazines to feed it.
The reason I went with the 20 practical, was because of the minimal work needed to form the case and it feeds from any .223 magazine without modification.
I've searched, but have come up empty in my quest.
