Hornady Announces 6.5mm 100gr A-Max

Been around a few months now. Some of the guys on the forum have tried it. It seems to have the ogive from the old 120, not the 123 designed for the Grendel, though!

That's strange that they didn't use the better 123 ogive. Perhaps a technical issue with needing bearing surface, if I were to give them the benefit of the doubt? But, then, Lapua, has a very sleek 100gr. Both 65G and all the bigger 6.5s have room for plenty of ogive. Why needlessly limit the BC? Hmmm. . . .

Regardless of what could have been, a G1 BC of .465 coupled with a muzzle velocity of close to 2800 ft/sec in a 24" barrel makes this a respectably flat-shooting bullet at all ranges. Naturally the Hornady page is silent on whether the bullet is suitable for varmints or larger game, but if it is suitable for deer-size game, then this could be a very nice all-round bullet.

And some folks say that the Scenar ballistic coefficients are overstated. "Interestinger and interestinger..."
More seriously, the Amax has that plastic plug, which allows for a very small meplat. That could be a partial explanation for the apparent conflict.
I suppose one could set up a chronograph at 500 - 600 yards and compare velocity loss versus predicted.
I wonder how many screens would be sacrificed before enough go through to get a decent velocity average?

The problem is that it will be hard to tell the difference between a BC of .465 and one of .425 until the range gets really long. For example, using a muzzle velocity of 2800 ft/sec there is a difference of only 0.2 MOA in drop at 500 yards and 0.9 MOA at 1000 yards.

It's really difficult to make a truly bad choice for deer.

Originally posted by bwaites View PostI'm sceptical that it is really .465. The 100 grain Lapua is only .424, and the 108 grain is .465. I can't figure out how something that blunt can carry that high a BC. The 100 grain Berger is only .370, and it is visibly sleeker than the 100 Hornady, though I'll admit that is just from pictures. I'd love to see them alongside each other!
We probably can tell the difference between .390 and .465 at 500 to 1000 yards.
