TZ,

308 is my primary rifle for deer and feral pigs.

Couple of suggestions fwiw.

The 130 Barnes TTSX is pleasant to shoot and performs wonderfully.

The 150 Partition wells well too if a lead bullet is preferred.

Varget and a F210 works well with both, as well the whole range from 135 - 185’s.

As others have posted 1:12” will work nicely, up to 185 Bergers in my experience.

Great deer hunting choice, enjoy.
