impala projectiles
@ 04:27 pm (GMT) |
Thomas Kitchenwas in a hunting shop yesterday and saw these http://impalabullets.co.za/ thought they were bit odd and interesting has anyone tried them or know anyone that has. i dont think i would bother changing to them but its always interesting seeing different designs of projectiles |

Alvaro Piqueras Alonso-LambertiRe: impala projectilesHi Thomas;Very interesting... I would like to add another two to the mix: GPA solid expanding (french made) http://www.cartouches-sologne.fr/eng/gpa.html Lutz Moeller solids (very confusing web, mostly in german). Link to the 123gr .308" bullet (also solid expanding) http://lutzmoeller.net/7,62-mm/30-06.php Cheers! |

Nathan FosterRe: impala projectilesHi Thomas, yes I have tested Impala bullets. Velocity was a key factor regarding the wadcutter profile. The smaller the bullet, the more velocity is required to impart trauma if using this typoe of bullet design. See also my meplat article in the KB.The Lutz Moller designs were originally based on GS custom bullet designs. I have not been able to determine any major difference in wounding between a homogenous bullet that loses its petals or one that retains its petals. Both designs are reliant on high velocity for maximum trauma along with a lower SD to increase target resistance. This is why we have seen weight reductions within the homogenous copper bullet designs. To increase wounding potential at lower velocities, the bullets need to lose more weight. But for the most part, all we are seeing is bullet makers try to make bullets that can be driven faster at the muzzle. Few people have addressed down range aspects for those shooting out to long ranges or using slow cartridges or very basic book hand loads. What we need is a copper bullet that can lose 50% weight for mid range work or 75% weight or more for long range work. The SD can then be increased to regain penetration in lieu of fragmentation with the bonus being an increased BC. All of this has been addressed in my second book- Long Range Cartridges. |

Jake longRe: impala projectilesNathan, thanks for the break down. Have you seen or used these bullets? They're starting to pop up around here but don't know anyone using them.Cutting Edge Bullets Match Tactical Hunting Bullets MTH or Lazer |

Nathan FosterRe: impala projectilesI am watching Cutting Edge closely at the moment. They seem to be ahead of others. have not tested, just watching results from readers at the moment. The Raptor bullets are worth pursuing. There is also a .338 frangible homogenous bullet. Very promising indeed. |

Jake longRe: impala projectilesNathan, the Raptors look pretty slick. Only concern is they run light. You could get some excellent fps with them but do you think they would tackle game up to 700 lbs? given that, impact velocity doesn't drop below their recommended 1500fps. I would be willing to give them a go on my caribou (400 lbs) hunt in Aug with my .270..264 raptor 110gr max .277 raptor 115gr max .284 raptor 135gr max Thanks Jake |

Bob MavinRe: impala projectilesG'day guys & Happy New Year!!!A couple of my mates did some testing for Woodleigh Hydrostatically Stabilised bullets with very good results on big Samba Deer. Bob |

Thomas KitchenRe: impala projectilessounds like some designs have some merit but don't really offer a major advantage. be nice to have some real decent projectile produced outside of the usa struggle to get the projectiles we want down here in nz |

Bob MavinRe: impala projectilesFor normal hunting ranges out to say 300m my favourite projectile is the Woodleigh protected point. I use them in my 308, 30-06 & 358 Winchester. They've never let me down, hold together and more than double in diameter. Around $1 each but if I have a special job that's what I use.Bob |

Nathan FosterRe: impala projectilesHi Jake, yes- therein lies the problem. Promising but still some way to go regarding the need for high BC bullets. From what I am seeing (reader input), the raptor "should" do the job. Note the word should- means I am lacking experience and offering opinion only which is therefore unreliable. But for 400lb animals, a 115gr partially frangible homogenous copper bullet should have both penetration and reach (there is that word again). I really need to test these bullets for myself at some stage (bullet donations welcome!).For your Caribou hunt and of the more traditional designs, you can try the following- 1- Work up loads with the 150gr Nosler Partition, look for accuracy sweet spots between 2900-2950fps. 2. If above does not pan out. Try the annealed 150gr SST, again look for sweet spots between 2900-2950fps. You may have to take shots at extended ranges due to any lack of cover so the bullet needs to be able to shed a degree of weight for trauma at lower impact velocities- yet still hold up fairly well in close. FYI for readers unfamiliar with Caribou, Caribou are similar in weight, muscle and bone density to Red deer. The largest specimens can run up to the size of an Elk, in NZ similar to Red / Wapiti hybrid to full blood Wapiti (Roosevelt Elk). |

Thomas KitchenRe: impala projectilescheers bob there's so many options its crazy really. might look at them they bit dearer here but i did put my name down for some 270 180grain woodleigh don't know if they havent turned up or the gunshop forgot to get hold of me. i was going to try and hollow point/ open up the front to do a trail boss load for shooting over bailing dogs. i might give those partitions ago and stay away from homogenous bullets |
