Range Report .308 ammo type for Tikka T3x Tac A1 20"

[NthDegreen]

HI all, I'm separating this from a different post. I have not received but would like to pre purchase a few hundred rounds of a few types before it arrives:
Tikka T3X TAC A1, .308 win, 20" barrel with factory muzzle break.

Please give me any feedback about what you found worked well and what did not- for long range accuracy, for practice, and for deer/elk hunting.

I have at my disposal- ammo selection from MiwallCorp.com locally which is where I will shop at..

Thank you!

just looking for brand/grain load/etc.

I'm thinking this for practice:
Magtech 7.62x51mm NATO M80 147 Grain Full Metal Jacket - 400 Rounds - Brass Case


And then maybe this for better/hunting:
Federal Power-Shok Ammunition - 308 Winchester - 180 Grain Soft Point
or...

Winchester Deer Season XP Ammunition - 308 Winchester - 150 Grain Extreme Point

or
Federal Power-Shok Ammunition - 308 Winchester - 150 Grain Soft Point

or

Winchester Super X in power point 150 or 180 grain??
