    "Enables reloaders to duplicate certain factory loaded ammunition" What "certain" Factory ammunition might they be referring to?

    Check the data. Vs what is written on a box of factory ammo. I loaded it for 44 mag pretty sweet stuff. I have never tried to duplicate factory ammo. I look for accuracy.

    Vista Outdoors owns Alliant, Federal, CCI, Remington, Speer, and Estate. It's only logical that they use the powder they manufacturer to load the rounds they create.

    I know people love to state that factory ammo is made using proprietary powders not available to reloaders, however it only makes sense that if a powder is so much better suited than anything else available for a particular cartridge/application it would make sense for the powder to be sold to reloaders.

    That's what BE-86 was used for when it came out in 1986, before they released it to us as canister grade powder in 2014. It was one of the powders they were selling ammo companies that we weren't allowed to have.
    I wonder how many of us were shooting it in our factory loads and didn't know it. I expect a lot. It had been available to ammo companies for 28 years before they finally decided to release it for retail canister grade powder.
    I expect 300 MP was the same deal. It was sold as canister grade to us about a year after BE-86 became available to us.
    Some time in 2015, who knows how long they had been selling it to ammo companies before that.
    300 MP had a much lower popularity and usage being it is a slow magnum powder so it's popularity isn't as high as BE-86 with it's burn rate right next to Unique.
    That's about the only way you'll find out what factory loads is to do what CoalCrackerAl said.

    The biggest challenge with 300 MP is that there is so little Alliant data for it. Many folks buy a powder primarily for one or two uses, but like knowing that data will be available so that they can try it in other applications where it would work well.

    Contrast the Alliant data with the number of rifle and handgun loads Hodgdon lists for their similar burn rate powders Lil Gun (original use was a 410 shotgun powder) and H110.

    And for what it is worth, 300 MP may very well be a better powder than H110 or Lil Gun. H110 and Lil Gun are considered finicky and/or problematic by many (myself included). I moved away from H110 and stayed away for Lil Gun even though they are both very popular.

    I've done exactly as you, avoided powders that only function well under certain conditions or have special requirements. H110/296 have and never will grace my bench. What's the issue with lilgun???

    As previously mentioned there are tons of powders that are available to the industry and they can also order something that doesn't currently exist. Providing a powder used by a company not previously available means you can replicate their loads.

    They are basically saying you can duplicate velocities obtained by certain factory ammo. Something that can be accomplished by virtually any powder available to reloaders. 300-MP is a magnum powder and thus can obtain legitimate magnum velocities, something some other powders may not.

    Welcome to "Marketing Speak 101" !

    What they are admitting is that while spherical powders typically meter much better, they often lack power density. That is, they typically take 20 to 40% more powder by weight to match the velocity of other powder shapes. In turn, this 'lower power density' can keep you from physically packing in enough powder into the case to reach elevated magnum velocities.

    What they should say is that: MP-300 has a higher power density than typical spherical powders. And this allows the reloader to reach magnum velocities, while still retaining the superb metering qualities of spherical powders.

    But they can't say that without having you question the power density of other spherical powders. :D

    LG runs hotter due to more nitro than the W296/H110. It also has warnings on not to use it with light bullets in revolvers. Known to erode the forcing cone.

    H110/W296 I use a lot of in my 458 SOCOM, and heavy 357 mag loads. Works well if you use it in the right application.

    To be fair to 300 MP, the Alliant guide is all around pretty bad and user unfriendly. For a number of the bullets they give load data for there is only one powder listed.

    The old Lyman manuals used to list "factory duplication" loads but I don't know for sure of any factory loading Lyman's cast bullet patterns and the listed canister powders. I can't say for sure but it could be that Alliant is just saying, "This powder duplicates what factory powders will do." Which is probably pretty accurate.

    H110 has a pretty narrow range that can be loaded, but I've not found it to be finnicky if you stick within that range.

    I used to think I wanted to duplicate certain factory loads until I realized that what I can make is better than any factory loads in every measurable way

    Lee's book has data for 300 MP.

    Concur with both statements regarding the old Lyman manuals and the factory loaded cast bullet ammo (I am not aware of any either). The Lyman 44th and 46th edition do list factory duplication loads while the 50th edition does not. My sentiments are that Lyman is listing factory duplication loads as those that match the advertised velocity of factory loads and not saying this is the powder the factory uses. Both older manuals also list the potentially most accurate loads.

    My 45th does as well and I wish they brought that feature back. I love that nossler list best load for each powder.
