I dont think the Military will release that information... but i do know that the military likes to use IMR 4064 in the 7.62X51mm ammo for rifles and machineguns... i just dont know if they use it in the M-118LR ammo as well...
Let me call a few friends up and ask... if any one would know it would be them.
Reloader 15 was the original manufacturer for the test ammunition... but it was to dirty of a powder if you ask me... IMR 4064 has allways been a military favorite... since IMR was formerly (possibly still is?) owned by DuPont wich had very large military contracts dating back the the mid 1800's.
Well, frankly, no, its not a good hunting bullet. Will it work? Yes, its all about shot placement. But these bullets are designed for match target shooting, they have a thin jacket and are not designed to expand. They fragment quite easily and penetration and weight retention is not good.
On a light animal like a mulie or whitetail, they can work, but its not recommended.
M-118LR (175gr SMK) works good for huntin the 2 leged varmints of the world... but im not quite sure it would be the best choice for hunting Game. The copper jacket is known for full seperation from the lead core... wich works fine for the 2 leged varmints some people hunt. But it wouldnt be a good choice for other game...
The Barnes All-Copper Triple Shock X-Bullets really should be considered as an all around bullet. Quite a few people have got really good accuracy with them, there's no jacket to seperate, and they come in boat tail hollowpoint form. They seem to penetrate very well, open all the time, etc. The only problem with them is the cost. You could use it on two legged varmints as well as regular game. The BC is pretty high as well.
I know I harp on these all the time, but I think they're a better (if slightly more expensive :wink: ) mousetrap.
Like Mel said though, its all about shot placement.
The best long range hunting bullets that i can find are Lost River Ballistics bullets ( http://www.LostRiverBallistic.com )... but just the bullets (per 20) run more than a box of high end ammo. :? The BC is high... up to .715 in .284 with a 160gr bullet and .894 with there 773gr .50BMG load. Here is a list of there bullets listed by caliber and BC... shown in a chart next to all other major manufactures with there bullets and BC. http://www.lostriverballistic.com/LRB/O ... tories.cfm As you can see... Lost River is obviously superior. Only flaw with there bullets is the price of shooting them...
And for all you .300 RUM shooters out there... looking for match grade factory ammo? Lost River makes it... its about 80 bucks a box.
At one time the M118 LR sniper and match grade ammo from Lake City was loaded with 175 gr SMK, 43.1 grains of RL-15 in LC match brass and I guess their own in house primer. I have loaded this load in FederalMilitary cases with CCI-Br2 primers and either 175 gr SMK bullet or 178 gr Hornady AMax bullets or Berger 175 gr VLD bullets all with very good results. Velocity is around 2655 ft/sec. I load the smk and the Amax to 2.825" COL and the Berger VLD to about .007" from touching the lands. The Berger load is the most accurate but will not fit the magazine. In this load, the RL-15 powder shoots very clean.
