My names Brody Colegrove. I live in Waverly Ohio and i am 16 years old. I have been lurking here for a while and really like this site. i have a borrowed remington 700 in .22-250 that i really like but i cant do anything to it so i want my own. My question is. What is the ballistic advantage of the 6mm over the .243? i want this gun for longer range coyote hunting. I appreciate any and all input. Thanks in advance.
