My dad shoots 175gr Federal Terminal Ascent. I think that and the Trophy Bonded Tips are the best bullet design of all bullets.
Best of all worlds:
Bonded lead in the tip for expansiom
Ballistic Tip to help cut thru the wind
Solid copper shank at the bottom that it physically cannot pancake
Aerodynamic profile
Not knocking any of the other bullets, esp Bonded ones. But the TA also shoots sub-MOA clover leafs at 100 yds with my dad's. .308 and it's amazing to see.
For the .308, I'd also recommend watching what kenetic energy does at what range. A lot of guys want a minimum of 1500 ft/lbs of energy to effectively kill an elk. Plus you want whatever bullet your using to expand correctly at whatever velocity.
The literature (granted I know it's from the manufacturer) says the TA has 1503 ft/lbs at 400 yds.
Several other manufacturers say their 308 ammo is 1500 ft/lbs is 300 yds or 350.
So take that into consideration also.
