Just picked up a RA Predator version in .243 for $399 at cabelas. I am very excited to turn this gun into my new coyote gun. Also, purchased a new Vortex Daimondback 4-12x40 scope for it for only $129 at Bass Pro. The help I'm looking for from you guys is what ammo I should be running through it. I know it is going to take some range time to really figure it out but I'm just looking to get some advice on what to look for. I know Winchester makes a 58 grain varmint-x round which will probably be the first box I pick up. I appreciate any advice or experience with this gun.
