My experience with the Light Magnums wasn't too good. However Hornady customs and my FN mauser just sang a sweet 1" song often with three holes touching out of five. Ballistics data is skewed for the simple fact the the majority of the manufacturers don't actually chrony the load they use pressure barrels for the data. I've also had good luck with Winchester silvertips. I load my own now but will still pick up a box or two of factory ammo for the season.
