    Hi Everyone,
    So with my Spolar Loader I got 2 shot bushings.
    One for 1oz and one for 1 1/8 oz.
    These are both for #8 shot.
    The I.D.'s measure .651 for the 1 1/8 oz and the
    1 oz is .619.
    My question is what are the I.D.'s of both for # 7 1/2 shot???
    By the way, the Spolar is an absolute work of art!!
    Smoothest loader I've ever had.
    Thanks in advance,

    So I took "grnberetcj"'s advise and just contacted them via their web site.

    Asked them for the I.D. size and also how far charge weight would be off

    if I used the #8 bushings for #7 1/2 shot. Let's see how long it takes

    for a response.

    All depends on the alloy of the shot.. Only your scale can give you and exact answer..High alloy shot weighs less than pure lead shot..

    I would be curious to know myself. Let us know what Hornady's response is.

    My 1 1/8 oz 7 1/2 shot bushing measures .637 and my 1 oz 8 shot bushing measures .610. I auppose one of our calipers may not be exact.

    If you click on my above link, I have some shot and pwoder bushing ID's for P/W owners... however, since Hornaday uses nomenclature of thousandths of an inch for their ID's (A WONDERFUL IDEA), you can easily cross reference my chart to theirs.

    For instance: a P/W shot bushing #5 is a 1 ounce load, and my chart shows the #5 bushing has an ID of 0.602". I would assume that the Hornaday 600 would be a close substitute. I *think* Hornaday marks their shot bushing thusly. They do mark their powder bushings accordingly.

    To hlep you, P/W uses the following:<BR>
    <Bold>#3 = 3/4 ounce<BR>
    #4 = 7/8 ounce<BR>
    #5 = 1 ounce<BR>
    #5.5 = 1 1/6 ounce<BR>
    #6 = 1 1/8 ounce</Bold>

    Hey REA5339,
    I have a SPI Digital Caliper. So I took my 1" I.D. Gage Block and checked

    it. It's right on the money. So, two possible conclusions, either yours is

    off, or Hornady's quality isn't as good as they say it is! Try and check your

    calipers against a known reference if you can.

    Whiz, my PW drops a very accurate charge. Always measure with a RCBS Scale.

    Because 7 1/2 is larger then #8, would think that their 7 1/2 bushing is

    slightly larger.

    Have not heard back from Hornady yet.

    I just got off the phone with Hornady (don't like waiting on e-mails) and here's the numbers I got from the tech department...

    1 oz. Field (#6 and larger shot) I.D. = .608"

    1 oz. #7 1/2 I.D. = .606"

    1 oz. #8 I.D. = .597"

    1 1/8 oz. Field (#6 and larger) I.D. = .648"

    1 1/8 oz. #7 1/2 I.D. = .641"

    1 1/8 oz. #8 I.D. = .638"

    1 1/8 oz. #8 1/2 I.D. = .635"

    1 1/8 oz. #9 I.D. = .632"

    All shot bushings measure .999" in length.

    Hope this helps everyone. Garrett

    Well three days now and nothing yet from Hornady.
    Went back and measured their powder bushings and they
    are all real close to what they say they are.
    Still surprised at the shot bushings. Will just
    have to weigh them out and see how close they are.

    Heard back from Hornady!! Thanks ClaySmoke for calling them.

    Will get setup today a measure the actual shot charges.

    If they're off will post the results.

    Anyone know where you can buy a complete set of Hornaday bushings, not one at a time but a set?

    So I got the Spolar going and loaded a box. Here's what I got--

    Weights varied from 501.2 grns to 505.5 checking 7 of the 25.

    The load is: old style AA hulls, Win 209 Primer, 17.5 grns Clays,

    WAA12 Wad, Northwestern Magnum #8 shot. So the over-sized shot bushing

    is dropping a bit heavy as I expected. Will try it with 7 1/2 Mag

    Shot and see what happens. On the other hand, the Hornady 447 Powder

    Bushing is dropping 17.3 to 17.5 with the mean being 17.4 grains.

    Right where it should be. And yes, I calibrated my RCBS 5-0-5 scale

    both on the level and with Lyman check weights.

    Mike,
    I wish you would have called or e-mailed us. Our shot bushings are not stock Hornady bushings. Look closer at your bushings. We have marked them with an engraving pencil after we remachined them to make them better with hard shot. All Shot bushings and all shot bars from all manufactures throw light loads of hard shot because they are calibrated with chilled shot. Hornady’s are the best, because they are shot size specific, but we take them the extra step of making them as perfect as possible for high antimony shot. Your weights will vary a little from ours and between brands because antimony weighs less then lead and the percentage in hard shot varies. Also, keep in mind that one or two extra pieces of shot throw the weight off.

    Can you buy an entire set of powder/shot bushings? Well, yes and no. In all of my research, I've never seen anyone selling bushings as a complete set. That being said, I once found a guy selling an old store inventory of bushings. There were over 100 of them, some dating back to the Pacific era. These were made of brass and marked with numbers such as #2 or #17. The others were pretty much marked by size as the new ones are. Without the duplicates I wound up with about 90 various sized busings. Cost to me........$30. Unfreek'n believable, especially for a guy who has no luck at all, zip. I sold the surplus Herr on TS at $5 ea. Honestly, some of the sizes I bought were obviously for powders that are no longer sold. Some others were so odd in size i just can't imagine what they were ever used for. So, my advice is to check Ebay often and buy them when you can.

    ClaySmoke, what Hornady didn't tell you was their shot bushings are marked for soft shot and are conservative, meaning they do not want to throw more shot than is marked on the bushing.

    For example, I bought a bushing for each shot size and weight. The bushing for #8 threw light charges of real magnum shot (Lawrence and West Coast). I enlarged it to .648" ID and it now throws 492 grs of West Coast magnum #8, give or take a grain or so. Same with the other bushings.

    Cunninmp, try putting a piece of 3M black electrical tape inside your .651 bushing. That will reduce the ID and throw less weight. That rick was taught to me by Hornady Customer Service. The old timer I talked to said it would never fall out, and he was right. I still use a couple with tape inside them. However, most store bought bushings are going to be small, so I enlarge them with a rat tail file and sand paper on a mandrel, or a Dremel tool.

    I have about 40 or 45 bushings for my Spolar. For those dense powders like Titegroup, you need only a hint of powder and the smallest bushing , while with Green Dot you need "dump truck " sized bushing. I like to have them cover the spectrum of loading. I try to write down the bushing sizes I have , and buy more when I see them.

    I have always used the 7.5 Hornady bushing whether I was loading 8's or 7.5's. There are so many variables in reloading, such as the quality of shot and vibration of the machine, just to mention a couple, I never thought the difference between shot bushings made for 8's or 7.5's really made much of a difference.
