    It is a commercial blend of powders that is not available to hand loaders. You can seek load data from the various powder sites that will approximate the MV of the factory ammo.

    Also what 7MM are you referring to? there are about 20 different 7MM caliber cartridges. [:D]

    After looking at the brass I am planning to use I noticed that there are a few different kinds of remington cartridges, a few look kind of older. Will that make a difference in accurcy?

    Never heard of the 7mm Frontier mag?

    The only 7mm I have seen in the Vangards is 7mm-08 and 7mm Rem. Mag..

    I have had great luck with IMR 4350 in both though.

    It can, but to a noticable amount, that is hard to tell. Between the older ones and newer ones I would weigh them out and see if there is much of a weight difference. Just give them ALL a good look over to check for any signs of fatique, cracks, or streching.

    Hornady uses Frontier Brass (and owns them for that matter) for all of their factory stuff and if you buy Hornady brass it will be marked "Frontier". Therefore, if the brass is stamped "7mm - Frontier - Mag."
    This is a 7mm Remington Magnum.

    HTG - To answer your question (kind of), look up the listed velocity for the Hornady factory load that you want to duplicate. Then look up the loads for that bullet in a Hornady reloading manual. Find the powder that will fill the case and give the closest velocity. This will be much easier if you have a chronograph and can get actual velocities. Now, that load may not be as accurate as the factory loading, but that is the beauty of handloading. You can try different powders, bullets, primers, brass, and charges to find the one combination that your rifle shines with.
    Hope this helps.

    Grant Jense, a fish cop in Utah, tested Remington ammo for the Forest Service for years, He claimed Remington chonographed 200 fps slower than advertised, was that way for years. No big deal, the rounds shot well, just never met advertised velocities.

    Thanks,

    I am trying to duplicate Hornady ammo that I've had good luck with. Which is the 162gr 7mm BTSP interlock 2940 fps. The only books I have are kind of outdated. So I'm still wondering what powder to use? Is there a website that has that data?

    All of the powder manufacturers have good load data on their web sites.

    I really like ball powder (cooler flame temp) in the 7RemMag. I use T870 but you should look at Hodgdon H450.

    Either H-4350 or H-4831 should give you all the velocity the cartridge is capable of.....
