I just got a CZ-550 Varmint Laminated in 22-250 Rem. I reload all my cartridges and bought 55 gr and 60gr NBT´s for coyote hunting. I have a Nikon Monarch 5-20X44 BDC and a Vortex Viper 6.5-20X50 Target Dot ready to be mounted on my rifle. Not really sure which one to use. 1.-Which scope would you recommend?? 2.- How far you think i can kill a coyote with those noslers leaving my barrel al 3600 fps?? I´m sure i can hit them really far, but i´m not sure if they will go down. I was previously shooting them with a .243 win and 500 yd shots weren´t a problem, but this is a considerably smaller bullet.
