I hope to get a .243 WSSM for coyote hunting in the next few months. I currently have a .300 win mag for deer (slight overkill for a coyote, I know) and an AR-15 that I do not want to put a scope on. It is mainly a toy for me. My dad has a .243 that he does not use, and I will probably borrow it for yotes once deer season ends. I was looking at .243 bullets, and do not really know which to use. I thought about using the 55 grain, but I know that the wind will have more of an affect than on the 70 grain. I guess I was wondering if anyone can tell me what kind of damage I would be doing to the pelt with a 70 grain bullet, or would i be better off just using the 55 grain? Thanks.
