If you look a little closer at Hornadys ballistic charts they are showing their plastic tipped bullets with a 200+ yard zero while everyone else shows their 30-30 ammo with a 100 yard zero. Zero some traditional RN bullets @ the same range and at the same velocity and the difference is not nearly as dramatic. Spitzer bullets only help out at ranges well over 200 yards in any chambering.
If you look closer at the Hornady numbers, not only do they use different zero ranges, they use different sight heights, which affects the outcome, and they use their own 170 gr bullet for comparison. They are fine game bullets, but have the worst BC of any 30-30 bullets that I've found, making the leverevolution loads look better yet. Almost any other make of 30-30 bullet has a better BC than the Hornay 170 gr. Look at the Speers for instance, the 170's run about .290 BC, the Hornady 170's are under .200 I believe.
Hornadys trajectory numbers for the leverevolution bullet comparison are misleading at best.
I've shot Hornadys and Speers with the same loads used at 300 yards. The difference in point of impact was very noticable, the Hornady 170's dropping much more.
I agree, within normal range for 30-30 use, which I'd go up to 225-250 if one is able to shoot well enough at those ranges, the common bullets, sighted in properly, work fine. Not much is gained by the spitzers, and one has to keep in mind the velocity that the bullets will work well in. The only real advantage to the leverevolution that I can tell is that they maintain their velocity a little better, giving a
little more effective range because of the remaining velocity, rather than any great gains in trajectory over most mainstream 30-30 loads.
