150 nosler partition sighted at 100yds drops 12.5" w/ 1734ft.lbs at 300yds. Not a lot of difference to the 160gr Hornady stated above (15" and 1699ft.lbs).
Uh, you might want to check your facts and figures before you make statements like that Buck, the energy is actually on 1025 ft/lb on the Hornady. The velocity is 1699 ft/sec. Note: If you are looking at the ballistics table in Peterson's 2007 Hunting magazine, then don't you think is interesting that their listing for energy of the Hornady is: 2046, 1643, 1304, 1699, N/A for muzzle, 100, 200, 300, 400 yards, respectively. How in the hell does this 'magic' bullet gain energy from 200 to 300 yards. physically impossible.
The 270 is not in the same league as the 30-30. The energy of 130gr Noslers is 2705, 2310, 1965, 1665, 1400 for the same distances. Bullet drop of both calibers with a 200yrd zero is -6.5" for the .270 and -12.1" for the 30-30. I see a difference there in drop and 50% increase in energy at 300yrds.
And keep in mind that the Hornady numbers are based on a 24" barrel. Unless you have a new XLR, no one will get those listed energy levels and bullet drop from the typical 20" barrel. It will definitely be lower.
I am not arguing that the Hornady bullet and their binary powder system is a significant improvement. It's just not for me. It does not perform well in my 336 and therefore will never be used by me at short or long ranges.
