I would like a caliber capable of harvesting quickly at 1000yds, say mule deer even elk, but also will group well enough for me to begin my hand at some benchrest competitions. Any thoughts on a good compromise form the astute members, who obviously have more long range time and experience than I do? I have heard 300wthby would be good, and some of you guys agreed, but what would be your first choice and why? I will fireform and load wildcats if necessary, so that's no factor. Thanks in advance.
