Whats the best load for this range for coyotes? Will varmint ammo work? Whats the best all around twist rate for both varmint and heavier bullets (deer)?
Define what you mean by long range. I understand it as >600 yards. And by loads do you mean factory ammo? Under these definitions, I generally wouldn't use factory ammo and a cheap budget rifle and expect the accuracy needed for coyotes or even larger animals like deer.
If you are on a budget, I would suggest getting a used rifle, and a used scope. There are some great deals from time to time, if you look around and have some patience. Those cheap factory setups work for many deer hunters who shoot a 150 # deer at 100 yards or less. Now shooting at a 25# coyote at 300+ yards with a little wind can humble many hunters. The 243 can easily work on both.
I don't know your skill level, so I don't want to sound condescending. You could be a scout sniper and proudly wear a hogs tooth?
Realistically, with a cheap factory setup and factory ammo, 1.5", 100 yard groups can be the norm, usually at the >1.5". Stretch that out to 300 yards, known distance and no wind or mirage and 4.5" groups are your best hope. If you do your part. That works on deer or larger animals, but I prefer better on coyotes or smaller critters.
Good luck with your setup. Whittakers had a great sale on Howas. I bought a 6.5 Creedmoor and it is a shooter with my reloads.
