I'm going to have to disagree on Mele's case capacity question for the Standard 7-08.

According to Quickload, you can run the 162 gr. AMAX at roughly 2,750 using H4350, H4831, V V 160, and IMR 4350 and IMR 4895 - assuming you use a 26 inch barrel. If you go to a longer stick (28 inch), you can run them up to near 2,800 fps without exceeding 60,000 psi.

If you go with the 7-08AI, you get an extra 2 grains of powder capacity and jump up again on the velocity.

I would agree, however, that a straight 284 Winchester will get your 162 AMax to nearly 2,900 using the same powders and a 26" barrel.

- if BC is your ticket to happiness then you need to look at either JLK or Berger (their numbers are reputed to bea bit inflated) - both kick Sierra's butt on BC. AS to teh AMAX, they are ok, I tried some 178s in .308 - my main gripe was that about 1/2 of the poly tips were either damaged (as in bent over or crushed) or missing altogether when I opened the box of 100. Take that tip off them and you slash the BC by a BIG margin.

My QuickLoad lists the following BCs by Mfgr, and the following MOA come-up from a 600 yard zero assuming the same muzzle velocity (everything below 180 grains 2,750 fps 180 grain 2,700 fps).

Hornady 162 gr. - .625 - 17.02
Berger 168 gr. - .630 - 16.93
JLK 168 gr. - .690 - 15.89

Sierra 175 gr. - .608 - 18.55

Berger 180 gr - .686 - 16.67
JLK 180 gr. - .738 - 15.86

There is no quesetion that if you can afford to shoot the JLKs - they are your ticket to long range happiness.

Mele-

Remember that the Lapua 123 is actually only a 108 grain bullet (the name is confusing - at least it was to me early on), so you can push it significantly faster than the 120-130 grain projectiles at far less pressure. Depending upon the cartridge used (.260 versus teh 6.5x284 vs the 6.5x55) there is a point where the Lapua 123s speed overtakes the higher BC of the heavier bullets (except in the wind).

Damn another error in my Quickload program - I just visited the Lapua site to verify what I had said, been told, and what my Quickload program says - BUT they were WRONG - you were right the Lapua 123 weighs 123 grains (8 grams). :oops: :oops: :oops:

Gotta go back and reevaluate some of my loads with the new bullet weight.

Gotta write that clown at Quickload another email about an error in the program :evil: :evil:
