    Hey guys I just bought a 300 wby and I'm trying to find a good load using any of these for powder:

    H1000
    Retumbo
    Imr 7828 ssc

    And any if these bullets:

    Berger vld 185
    Berger vld 190
    Berger vld 210
    Hornady Amax 208

    Anything to get me started in the right direction would be awesome and greatly appreciated!

    Consider yourself lucky, b/c my Berger manual came in today...

    DO NOT start with the max load.....Work your way up to it 1/2 a grain at a time. Just trying to help you incase you are new to reloading.

    These are the starting and max loads my Berger manual lists for each weight bullets.

    185 VLD:

    H1000 - Starting: 75.0....Max: 83.5
    Retumbo - Not Listed
    Imr 7828 ssc - Starting: 72.5....Max: 78.7

    190 VLD:

    H1000 - Starting: 75.0....Max: 83.3
    Retumbo - Starting: 78.0....Max: 84.5
    Imr 7828 ssc - Starting: 72.5....Max: 78.2

    210 VLD:

    H1000 - Starting: 76.5.....Max: 80.5
    Retumbo - Starting: 77.5....Max: 81.5
    Imr 7828 ssc - Starting: 71.5....Max: 75.2

    Hornady 208 A-Max - My Hornady 9th Edition manual doesn't list the .208 A-Max for the .300 Wby Mag. Sorry.

    Hope the rest of this helps.

    Your awesome man!

    Really appreciate it and will hopefully be able to start some loading...

    Sometimes I hate how picky I am with my accuracy it can really burn a guy out on reloading lol just got done with my 308 and thought I was in the clear for a while then bang new gun....

    Thanks again!

    Have you noticed any temperature sensitivity with rl-25?

    I ran some loads using the 210 VLD with the powders you had posted up (to include the RL#25 that was suggested)

    The best performance out of all of them turned out to be the IMR with the RL#25 taking 2nd place.

    Here's the readout for the IMR powder:

    Hope this helps you some,...

    Is there a certain die set that is best for the .300 wby? Anyone know where i can get a used set or a new place to buy my reloading supplies online the closest place for me is about an hour away or more.

    I load .300 Wby for a buddy of mine (don't have one myself), but for all my belted-magnum cartridges, I use RCBS Neck-Sizer dies, since it is easier on your brass, and helps to produce less brass stretch.

    I got my press & dies, and most of my reloading stuff from Midway USA. Great people, great customer service, and their shipping is FAST!

    No

    I normally shoot between 40 to 60 deg no effect on accuracy

    Most powders will be effected If your in a real hot zone from cool early morning and as the day heats up.


    suggest find a set of original weatherby dies and you have a neck and FL all in one set plus bullet seater on ebay
