I am new to this forum and to varmit hunting, so forgive me for being a novice with questions. I am setting up a Remington 700 in 243 for coyote hunting. What bullet size is best? I am researching Hornady Superformance Varmit in 58 or 75 grain. Right now I am planning on new ammo, but might get into reloading later. Also have question on optics. I have researched Bushnell Elite, Vortex, Athlon, and Leupold. I am leaning toward Leupold VX Freedom in 4-12x50. Thanks for all your assistance!
