tell me about amax bullets

hornady is using amax bullets in there .308 tap series correct? anyway i keep hearing "amax this, amax that". 5.56 75g tap is regarded as one the most effective rounds for 5.56mm so i would assume that the guys over at hornady know what they are doing with .308 ammo but i have no idea what it does! i have seen a few jell shots and they look great but, does this stuff yaw and fragment like 5.56 or expand or what? what does it do on the other side of auto glass and similar intermediate barriers? are they velocity dependent to perform reliably in a target? (i know the .224 projectiles sure are) and why am i hearing so much hype (and at the same time so little factual info) about amax .308's ? some one throw me a bone here.

There's a whole bunch of talk about Amax bullets? Not out around Utah.

I know that they are accurate but they don't have any special reputation out west that I know of. Out here they have a good reputation for being accurate for paper punching but they don't have any real popularity for taking down big game. Most people I know use Nosler, Barnes, or Berger bullets. But then most of the people I deal with hunt animals that go from about 200 to 1200 pounds, some of which will eat you if they get the chance. Now the Hornady SST on the other hand, has a very good reputation for taking medium sized big game.

I just loaded 50 rounds of .308 155gr A-Max yesterday, on top of 43 gr of Accurate 2520 (which is a mere 0.2g OVER the max .308 Service Rifle listing in Hornady's newest manual, but still about 3.0 gr less than the standard .308 ammo listing with AA 2520 for bolt-type .308s). This recipe should be good for ≈ 2500 fps; not all that quick, but within the established pressure safety limits set for the M1A's op system.

I also loaded 10 of Sierra's previous 155 gr HPBT Match bullets. Difference is in the nylon "Ballistic Tip" type pointy end on the A-Max bullet, and I think that's all the difference there is. It's Hornady's answer to the Nosler Ballistic Tip is all, a non-deformable tip, which does also tend to move the CG (center of Gravity) backwards by differentially lightening the front end of the bullet.

That rearwards CG change usually results in longer-range stability, esp. if the bullet is in any way de-stabilized en-route to the target. Or if it temporarily wobbles as it goes sub-sonic (out @ about oh.... ≈800 yds?) but then re-establishes it's lower velocity spin-induced stability.

Later today I should have a range report available: accuracy & velocity.

I'll bet your velocities end up being closer to 2600 - 2625 FPS, assuming a 22" barrel, but your accuracy will probably be pretty nice.

For punching paper, not for terminal performance. At least in .308s

A-Max Bullets

My experience has been limited to an accuracy comparison between Sierra 168MK and Hornady 168 A-Max, both seated in commercial cases, CCI BR-2 primers and comparable doses of H4895. An LRB rifle in service configuration was used. The Hornadys out-grouped the Sierras by a significant margin at 100 and 200 yards, the max distance I shot that day.

More power to you if you can get 'em to shoot. Some have good luck, I never did.

great shooting bullet, but pretty useless on animals. i have shot exactly 1 deer with an amax bullet, and the results of a perfect heart shot were less than stellar. bullet jacket and core seperated, not good.

I called hornady and asked about the Amax for hunting. They do not reccomend it.so I then asked why is it used in your .308 tap ammo stutttering and stumbling words ensued with no
Definate answer given by them

The only reason why TAP (as in "double tap"?) ammo is an urban buzz word is because it was originally designed for LEOs so that they would have a bullet that would kill bad guys but not innocent bystanders. The light jacket works well on human flesh but it comes apart when it hits anything substantial, especially brick, concrete, cars, etc. The A-Max bullet was created for the TAP ammo and Hornady has marketed the bullet separately.

the AMAX bullet was not created for TAP ammo, its been around much longer than the loaded ammo. it is and always has been a target bullet. quite honestly, besides my personal experience with the AMAX, ive also watched coyote hunting vids where the guy used .223 TAP ammo, nothing like a bullet blowing up on the shoulder of a coyote with zero penetration. in short, if you like hornady bullets (which i do), and want to kill something, use an SST.

Cool

In Hornady's #7 Manual they state that the A-max is primarily intended to be used in target shooting. It's also not recommended for anything larger than medium size game. The A-max has a thinner wall thickness than the SST. Reason for this is that concentricity can be held to tighter tolerances for accuracy. Not good is that it is prone to fragment and not expand reliably. It lacks the penetration and expansion of the SST with its thicker walls and interlock. The SST was designed to hold together on thicker skinned, big boned, dangerous big game animals. The SST lacks only a little in the BC department, but I'll give that up for the better all around performance of the SST. When used for penetrating barriers, the SST wins again. I guess you can tell, the SST is my all around, everyday, all purpose bullet reload. dozier

I stand corrected, the A-Max has been around longer than TAP ammo, but they do use the A-Max in the .308 TAP cartridges for exactly the reason I mentioned. I should have said that TAP ammo was a way to market the A-Max bullet since it isn't very popular as a game bullet.

you are correct , its not popular as a game bullet, because it isnt one. now, and this is 100% my own opinion i believe hornady screwed the pooch on this one, because the AMAX is not suitable for game animals, that makes it absolutely unsuitable for defending one's self against the most dangerous animal there is, MAN! I wish people would really think this over, its not suitable for 150-220# deer, do ya think its suitable for a 200# man?
