    Default 300gr cast load for 45 Colt

    Have some 300 gr. LFNGC sized to .452.
    Also some W296 powder.
    Any loads to try starting on the low end?
    Shooting Ruger Redhawk 5 1/2" barrel.

    According to all that I've read , including win load books, w296 should not be loaded light. I wouldn't go below any loading books recomended load with this powder. There are a lot of other powders that will work well for lighter loads ( unique, 2400, Blue dot are a few). Also, if this is an older 45colt you have, win296 probably shouldn't be used at all and neither should info that you got from someone you don't know and trust. Get your loading data directly from loading books, not from a possible typo on the internet.LOL rbuck

    I just order a new Ruger Redhawk 4 inch 45 Colt today. Looking forward to loading for it. Here you go. Check out the attached files. H110 and W296 are for the powerhouse loads.

    Default Sweet

    Thanks for the links.
    rbuck, not many loads in manuals for 300 gr.hardcast bullets.
    I have four. As for light loads, I was wanting starting loads for 296.
    Any load data I receive would be researched before building and firing away.
    Ruger is a new Redhawk.
    Cheers!

    CUTTY - " As for light loads, I was wanting starting loads for 296."
    Cutty, as suggested above, do NOT use light loads of WW 296 for your "starting" loads. Nor should you use light loads of H110. Same powder.

    I'd not load any lighter than 20.0 grains of WW 296 or H110.

    I've been loading for a Ruger Blackhawk 4 5/8" bbl., .45 Colt for many years. I suggest 9 grains of Unique behind those 300 grains bullets, for "lighter" loads. (You'd be surprised what that load will shoot through, too.)

    Use your WW 296 when you want to cut in the afterburners.

    Just a suggestion.

    Default Little confused

    So, for an example, Hornady manual #7.
    Ruger loads, 300 gr. HP-XTP. W296 loads start at 17.9 through 21. gr.
    So it would be bad to start at 18 grs. for this bullet? I see 17.9 is 1050 fps.
    Aren't you supposed to start low and work up loads.?
    I realize this is a jacketed bullet and not cast, but still?

    My understanding from Linebaugh's writings is that it is not necessary to push the big bullets beyond 1200 fps or much above 30,000 cups...

    Confused,

    I can tell you that loads lighter than 20.0 grains of 296 with your 300 grain cast will not perform very well. What folks are trying to say is that 296 powder does not work well in a light load. When you asked for starters for the low end, that's what we thought you wanted.

    W296 and H110 powders are to be used at near max loadings. They also require a heavy bullet pull and magnum primers. Heavy pull means heavy bullet weight and a good crimp. Any load less than 20 grains with these powders and these bullets will result in inconsistant ignition and the possiblity of a squib especially in cold weather.

    A better powder for the 45 Colt is H4227 if you can find that but if you have already purchased the W296, use it as intended in full charge loads.
    It can be used down to the midrange of about 900 fps with the 300 cast.

    Your Redhawk and the 45 Colt are capable of pushing 300 grains to 1300 or more but there is no advantage to anything above 1100 fps with that bullet. Cast bullets will generally give higher velocity than jacketed of the same weight, with the same powder charge. Use good brass for your heavy bullet loads and a good crimp to keep them in the cylinder.
    Is there nothing so sacred on this earth that you aren't willing to kill or die for?

    Default Narrowed it down

    Settled on two loads for now.
    9 gr. unique and 22.5 gr. 296.
    Both shot well.
    Finally understand the 296.
    Now I just need to decide on some 250 gr. plinking bullets.
    What's the ideal lead alloy to use? comparing soft/hard lead.
    Or what's a decent bullet to try?
    Have Unique, Universal,Titegroup, and Trailboss for these loads.
    Thanks again.
