Just wanted to see what y'all would say. Mine was probably 300-315.
Alright I've got you beat. My longest I'm kinda embarrassed to say is 278 yards...
Yeah but knowing how you are I'm assuming you were using the .223 rem
Speaking of 223... my longest 223 kill with iron sights on a whitetail doe... 556 ranged yards with an AR15, and 3 other witnesses... but then thats all I shot at that time, often on a daily basis with irons out to 1000 yards at times...
