I currently have a Buckmaster 4.5-14 on my RRA Predator Pursuit and want to upgrade. Looking to keep it under $800. I have narrowed down my choices to either the 4.5-30 Bushnell Tactical or the Sightron 8-32. The furthest I have shot with the gun is 550 yards, but would like to be able to shoot out to 800 with the new scope. I also want to be able to use the gun for some coyote hunting and I have a feeling the 8x is not low enough. Do I need the 30x on the top? or would I be ok going down to a 24x scope? Which scope should I go with?
