Wondering. You have a .243 105 gr bullet with a BC of .543 shooting against a .300 WM 185 gr bullet with a BC of .549 both running @ 3050 fps. Both similar in BC would these cartridges be capable of the same accuracy? Will the heavier bullet win even though they both have similar BC. Example a 1000yard shot with a ten MPH wind. Can these two cartridges shoot similar groups?
