Aluminum Tipped 7 mm 162 gr Amax
@ 09:06 pm (GMT) |
Jim MoseleyAn old timer who once shot competition gave me three boxes of aluminum tipped amaxs. They are 162 grs and really look deadly. I've never seen these before and they were dated 1995. Anyone know the "bc" on these bullets and will they work on whitetails. I guess the loads would be similar to the current amax? |

John SmithRe: Aluminum Tipped 7 mm 162 gr AmaxIn my 1975 Hornady Reloading Guide the 162 boat tail hollow point in 7x57 has aBC of 725. Nathan will probably give you the BC of the aluminum tipped 162 grain bullets. |

Nathan FosterRe: Aluminum Tipped 7 mm 162 gr AmaxHi Jim, this was the formative design. Unfortunately I never got a chance to test it, it was only available for a short time. It will pay to compare lengths before hazarding a guess as to the BC. You may find that the BC is much the same as the curent A-Max bullet but the length will be an immediate indicator.Your bullets will be very soft now. They will be fine for your local game. |

Jim MoseleyRe: Aluminum Tipped 7 mm 162 gr AmaxThe current polymer tip amax : base to tip - 1.435"base to ogive - .735" Aluminum Tip amax : base to tip - 1.595" !! : base to ogive - .895" Found an old post on another forum dated 2008 which stated that the real BC was .710. That's pretty high. Guess I'll start with H-1000 or Retumbo due to component shortage of powders. Any suggestions are welcome. Should be an interesting experiment. |

Nathan FosterRe: Aluminum Tipped 7 mm 162 gr AmaxSounds like a nice long bullet Jim.I would simply run the same test loads as you have done before. Set jump at 10 thou. What is your current sweet spot Jim, I thought you were up around 72-73 grains H1000?. |

Jim MoseleyRe: Aluminum Tipped 7 mm 162 gr Amax72.1 grs / H-1000 seated .012. The bullet is quite a bit longer than the current Amax so case capacity will be less or using the 72 grs could result in a compressed load. Not sure. The 180 Berger has a length of 1.525 and this Tipped Amax has a length of 1.595. |

Nathan FosterRe: Aluminum Tipped 7 mm 162 gr AmaxOK, well hopefully you will be able to work up to a similar load. It will be interesting to see if pressures come on early. May pay to start at 70 grains and work up to 73 grains in half grain increments- stopping as necessary if pressure signs come about. Its certainly quite a lot longer bullet. |

Jim MoseleyRe: Aluminum Tipped 7 mm 162 gr AmaxFinally got to test the AT-Aax. The load is 70 grs of H-1000 seated .012 off the lands. Same as the polymer tip Amax, excepted 2 grs less powder. The MV is 3080, which is 40 fps faster and I assume that is due to the longer surface bearing of the AT. Shot a cowhorn buck on Tuesday at 80 yds just to test the bullet. The entry wound looks worst than most exist wounds! Shot just behind left shoulder hoping that it might squeeze between two ribs, but it hit square on and blew up with no exit wound. At 80 yds, that's 3200 lbs of energy, so needless to say it deer dropped like a rock. Sent bone bone fragments throughout the body and into the ribcage on the right hand side. Found one fragment that had cut the deer's throat and lodged in the skin on the right side of the neck. I did recover the aluminum tip and maybe 1/4 of the copper jacket in the skin just in front of the right shoulder. The hydrostatic shock wave crushed about a 3-4 inch section of the spinal cord above the shoulders. The bullet is very accurate. I have limited ammo so shooting is limited. Set up a target at 815 yds and carefully calculated conditions, and missed the 1/2 inch bullseye by only (1/2 inch)! Called it quits!! Will test another cold bore shot this week at 1100 yds. I'll try to remember how to post a pic :-) |

Nathan FosterRe: Aluminum Tipped 7 mm 162 gr AmaxDefinitely a fast killing bullet huh. Thanks for sharing these results Jim, much appreciated. |
