I like that 308 case, good little one and nice necked down to .264, with 100 to 140 grain bullets. My favourite is the 120 Grain Gameking.
The 308, I like the 165 grain, or the 180 grain, the 165 is like having an extra 100 yards on a 30-30 with a 170 grain pill. I really dislike 150 grains for 30 caliber, however, the weight is great fir a .284, or 270
If you need more than a 180 grain, like the 190 from Hornady, or a 200 Gameking, or Nosler, or Swift, then a 30-06 is better, but I like to 06 fire formed to a case like the 308, with less shoulder slope, like a
Brown Whelen.
I really think the 264 Remington is like a smaller 270 Win, not that much difference and it stands in well for a 243.
If you hunt mainly east, that combination, along with a few shotguns is all you need, along with a good handgun, a big one when hunting.
