    I've been shooting federal gmm 168 gr 308 ammo for years. As far as I'm concerned, nothing can touch the accuracy they have for a factory ammo. All the components are obvious as far as what makes up the cartridge, except the powder. Has anyone learned their secret or found a close match to what powder they use. There has to be something special they're doing to make a mass produced cartridge so accurate.

    Almost all ammo manufacturers are very secretive about their powders.

    Google "canister" powder.It should provide an explanation as to the how's and why's,to the differences between powder we reloaders use and what the big manufactures use.

    Reloaders take common powders and use exact amounts, use bench rest primers and premium bullets. We trim cases to exact length. By doing all this you achieve great accuracy for 1/2 the cost.

    Whatever their proprietary powder is, it will be similar to H335 or H380.

    I can duplicate their accuracy with both of those powders.

    Yes I'm a aware of the process, I've been reloading for years. I have honed my 308 handloads to the point of one jagged hole at 100 yards. My question is based around the fact that I know what work it takes on a bench to gain sub moa accuracy for a handloader. But we all know that there isn't some guy in the back of the federal factory loading each gmm case by hand. So they have to be doing something to gain the accuracy out of a mass produced load.

    I would think they are setting up the powder dispensing to be more accurate on the mass production scale.

    Have you guys ever heard of the OCW theory? Dans theory is based on why the gmm round is always sub Moa in any rifle. It also ties into optimum barrel times theory. Do a google search for both and give them a read. Good stuff.

    I just read it, and I must say it brings light to my question. Fascinating stuff.

    Federal used Accurate powder. I called them a couple years ago for some load info on some bullets that were made for them, but they discontiued. The tech told me all they used was accurate, but could not tell me the powder or charge.

    For sure. I ran that test last week and was able to see what results I was looking for. One of the main statements though he mentions is that the rifle and shooter needs to be capable of sub Moa. I've watched a buddy try it twice with an AR and him having a hard time holding on target spray rounds everywhere. It was inconclusive obviously.

    For sure. I shot my first one last week. It worked just like he mentioned. Found three groups that impacted the same poi. They were 47.6, 48 and 48.4. At some point I'd like to load one round up of each charge and see it stays sub at 100. He also mentions brass changes. Somewhere in the reading he took a win, rem and some other piece of brass with different brands of primers and was still able to form a group. I don't know if you've picked a load from previous testing but you can load one round .7% above and below and shoot a group. Two of them will group and one will be outside the group. It'll tell ya if your close.
