I can't say from my own experience with the a-max as I too have a box but have not shot anything with them yet.
I would hypothesize that they should do as well as a Match king,..which seems to have quite a few followers here. I wish I could tell you more,..but like I said,..I havn't loaded my 162gr a-max bullets yet,..so I am working from information that I have been given by other shooters.
You know JustC, there's someboy around here that has taken a bunch of coyotes with that 162 A-Max at very long ranges with pretty good results. But i'd think that there's got to be a world of difference between terminal ballistics on coyotes and elk.
338-378, I have seen P.B. #2,...and I would have to say that you are correct images/icons/grin.gif
sscoyote,...I take it you are the coyote vs a-max guy? images/icons/wink.gif I have been planning on loading some up for my 7mm mag,...but have been working with a 300RUM lately and have never even tried the first recipe in the 7mm yet. images/icons/frown.gif So many bullets,...so little time.
Check with your dealer about Norma Diamond Line, they have both formats; moly #66508 and copper #66509. It is a 130 grain HPBT with .548 BC. You can push it up to 2,900 fps with GREAT accuracy and Vihtavouri N560.
I don't belive I would attempt an elk with the A-max line of bullets.
They may be good for deer and Lopes but, elk are 6x to 8x bigger and the shoulders are massive in the big bulls.
The MKs jackets are thicker then many of the so called hunting bullets and have performed well for us on elk.
Even the JLK and Berger jackets are thinner then the MK but, also have done well on elk from reports.
If the barrel twist was an 8 to 8 1/2 and I was using a 6.5, I would use the 140 to 142 MK bullets in it especially if the range was at 600 to 800 yards. You will be surprised as to what it will do.
Of course shot placement means a lot.
I agree based on my deer experience with the A-max. Three very dead deer but they were all shot in the lung area without hitting any bone. If I knew I would hit the elk in the lung area for sure I would try it. My guess would be they are not strong enough to penetrate an elk's shoulder. I'd like to cut apart a 30 cal JLK to compare jacket thickness to my 7mm MK, A-max and Cauterucio disected samples. Could someone mail me one, please. I may use a 30 cal JLK on elk this fall.
