Not long ago I did a field test between Federal, Winchester, Remington and Hornady. To make a long story short, the 30-30 I used was sighted in at 100 yards with Remington 150gr. At the end of the tests the Hornady "Leverevolution Ammo" shot 6" higher than the Reminton, Federal or Winchester. 5 shot groups were less than 3/4" with Hornady, 1 3/4" with Winchester. Federal was the worse at about 2". All shots were from a bench using a Caldwell lead sled with 3 bags of #7 shot. Since then I have tested the .44 mag LE ammo along with the 45-70 Hornady with about the same results. I know some rifles like different ammo, but I am totally impressed with this new LE ammo. This last deer season I dropped an 8pt. at 187 yards and he never moved. Wound channel went through both lungs.
