Best factory 7mm cartridge for whitetail?

[Hi Ball]

Bucktrack7.........I'll give you my take on the 7mm mag and bullets that suit me for hunting antelope to elk! I like the 160 grain because it has great sectional density, meaning it penetrates very deep into tissue OK. Now after all it is only 20 grains heavier than a 140 but it's trajectory is less than 1 inch lower at 300 yards. If you hit that deer at 100 yards with the 160 grn bullet it will cause far less meat damage as well.

The other thing I like about the 160 grain in a bullet like the Nosler Partion, TBBC or Swift A Frame, is that it stays together and 95% of the time (unless shooting from end to end) give you that pass through shot on your deer. I realize that many may say the need for premium bullets is NOT warranted! However, I have found over the years that such bullets are a cheap insurance policy in your hunt being successful. Federal loads Nosler & TBBC bullets in their ammo.
