Slim's Review of SightMark Core SX 10-40x56mm CBR Rifle Scope

I put one one my custom 300 win mag and hit a prairie dog at 1200 yards with a 15mph crosswind. On my 3rd try. But I needed those first 2 shots for my spotter to guide me in. The only issue I had was the weight made it hard to keep it solid in the rings. So once I got some good rings I was hitting hole in hole at 300 yards. It has a nice thin crosshair so it dosen't cover small targets at long distance. The price is great. I got a sun shade for it and with the 56mm objective lens finding targets is much easier than others I've used
Pros:
  • good clarity
  • Paralax adjustment
  • illumianted reticle
  • 56mm objective collects a lot of light
  • Thin crosshair
Cons:
  • Finding scope rings that don't let it slip on larger caliber rifles
Best Used for:
  • Bench rest rifles
Would Recommend: Yes
