I agree that it looks a lot like the light/heavy magnum ammo. Just seems like a different name and more caliber offerings/bullet weights. May not be a big difference over handloads but it is a sight better than standard factory stuff. I wonder if they've over or understated their published numbers though. In the video on their website it shows Craig Boddington shooting 165 grain 30-06 loads and according to what he was saying the chrono showed, the numbers were a little higher than what Hornady claims for that load. All in all though Hornady makes good ammo at a fair price and I like the idea of it, especially for someone like me who has yet to get into reloading. I've been using the Heavy Magnum loads in my 338 and really like them. Guess I will switch to the Superformance when my stockpile runs out.
