What is the fastest hunting load you have worked up in the .308 win and still kept pressure signs in the safe zone.

If I was bumping 2,950 with a 150 in a 24" tube or 2,750 with a 165, I'd feel like I was "there" with regards to top-end. The .308 doesn't need to run at absolute redline to be effective. I'm good with 2,850 and 150's in a 22" barrel, shooting H4895. Made about 2,880 in another 22" gun with 155 Scenar and RL15. Both shot well. I think that 155 Scenar offers a lot for a little.

51.5gns CFE223 and a 150gn Nosler ballistic tip averaged 3003fps out of my Rem 700 .308 22" bbl, which is pretty much exactly what Quickload says it will do. In terms of velocity, text best powder with a 150gn pill in my rifle is Alliant PowerPro MR-2000.

The Ramshot Manual shows Berger 155 VLD, Hornady 155 AMAX, and Sierra 155 HPBT Match with 57.0, 57.9 an 61 grains at 59K, 58K and 59.5K using TAC.

The Scenar is most like the Sierra HPBT Match. Where did you get 75K?

My copy was a little older, but the new load book from Ramshot sure isn't in the 75K MPSI range if he adds 0.3 grains to the Sierra load.

I'm getting a little over 2,880 fps from the Barnes 150-grain factory load in a 22" Remington 700.

I know you were an officer, so I suppose I'll have to dumb it down for you. 46 grains is significantly different than the 57 to 61 in your post (that's more powder than a 30-06 will use with TAC and 155s). 2925 fps in an 18.5" barrel is more than Ramshot is achieving with their 24" barrel. A barrel 5.5" shorter than the test barrel is going to be slower, not faster. So, since velocity equals pressure, the 18.5" 2925 fps load in question is either a: significantly over pressure in order to achieve such high velocity, or b: the poster's chronograph is off.

You win. I looked at the wrong table.

My bad. Thanks for correcting me, and I mean that.

No worries! Hopefully it's a chronograph issue and not an over pressure issue, as blowing a primer or worse is a bad deal!
