Best bullet for .308 with 748 powder?

[Shane Lindsey]

With the powder you have I would try either 152 hammer hunters or 168 barnes TTSX. Steve at hammer says that they get 3000 FPS with the 152 hammer hunters and CFE223. I can get 2825 with the 168TTSX and cfe223. Win 748 is a little faster per the burn chart I have so you should be able to get close. With most TTSXs barns recommends 1800fps min at impact, the 168s are one of the exceptions they recommended 1500fps for the 168. I would recommend you add 200-300fps above their number as insurance.

If you are willing to change powders I would recommend the 151 absolute hammers. The absolute hammers work differently and work best with faster for powders for a given cartridge. Iam just about finished working up a load using Alliant Power Pro Varmint at ~3130fps. From talking with Steve at hammer he had had similar results with ramshot TAC (I don't have any/haven't found it locally).

update: my velocities are out of a Winchester m70 ftw with a factory 22in barrel.

With CFE 223 and the 152gr Hammer Hunters I was getting about 2820 FPS with my 20 barrel and Lapua cases.

With Shooters World Precision, I am getting 2815 FPS. Temp stable. At my sea level elevation it falls below 1800 FPS (Hammer recommendation) at 525 yards. Wind is the biggest issue with these. The 215 has 2.9 MOA vs 4.5 MOA of the 152. Not too bad at 525, but add another 100 yards and wind call excellence must be spot on.

The CFE was definitely top end so not preferred in the heat of summer months here.

When I first started loading for the 308, my Speer manual listed 748 best for the 150s and 760 for the 165s. It worked swell too. I personally settled on 760/165 NBT (back when they were pretty soft, the 165 had less lead up front and worked just fine at 308 speeds) shot an Axis buck at 230 long steps, Partition-Like pass through both shoulders.
