Re: 243. win for varmints and coyotes!
The .243 Winchester is an excellant coyote round. Take the time to work up a load your rifle is accurate with and practice, not from a bench, that's for sighting in, practice your technique. How many times have I heard a rifle is fit to become 'tent stakes' when all that was needed was some load development and practice on the shooters part. I'll assume we are talking factory rifles here, and some of this goes for custom barrels as well. It's very hard to state, "I want to shoot a 65g. V-Max". What if your rifle doesn't like it even though you've tried many different primers and propellants and seating depths? Try another bullet and combination. Those heavier bullets usually have better B.C. and more foot pounds of knock down energy and thats what it takes for clean, long range kills on coyotes. This is where the 6mms shine over the .22's . Even in custom barrels with fast twists, shooting heavy for caliber bullets, the 6mm's have higher B.C.'s than the .22.s. All this said, I'm shooting either my .22/250 A.I w/ 60g. SP or my 6X45mm w 80g. SP, both custom barreled. I choose my shots carefully and make clean kills with either rifle.
