Prairie Dog demolition tool: AR in .223 or .224?
These old eyes can't hit them at 200 yds with my Marlin Mountie anymore so it's time to step up. I also want to be able to deal with the dogs that used to be "out of range".
Fired Distinguished Expert with M-16 (and younger eyes) so I'm familiar with the platform but haven't "built" one yet. Assume I'll be handloading the hunting rounds.
First question for the experts is: which caliber? At what point does the .224 start outperforming the .223?
Second question, once caliber is determined, what barrel length and twist?
and third for now: suppressor or not?
Looking forward to learning a lot.😃
