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).

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:
