I don't usually take sides with wise *** aka wildrose but a 178 amax has a .495bc the 180 interbond sst has a secant ogive virtually identical to the amax, actually a little longer, and has the cannelur "crimp" you speak of and carries a G1 avg of .547, only .58 at over 2600fps. And it is bonded, really do you think Hornady is going to market a bullet designated as "match only" as a hunting bullet, no they won't. I hunt with amax's they are very effective at extended ranges but up close they are extremely frangible.
