Data - Sabot Diameters

[sabotloader]

kingofcoins from Modern Muzzleloaders spent some time measuring and empty and loaded sabots and completed a spreadsheet with the information.

Really looks like a lot of the information could be really helpful for your search for the right sabot.

One thing to keep in mind sabots will/do compress as they are pushed down the bore. A good example of this is the MMP Blue 40/50 cal sabot. Loaded Dan mic'ed it at .5075. This sabot will load in my U-Mag fairly suggly(not tight) and yet it will also load into my Omega which is much tighter. Not all sabots have the ability to compress as much as others.

Anyway here is Dan's spreadsheets...

Folks can create a Shortcut to the above Table here:

then they have it in the future in their "Favorites", or better yet, create a "Hunting Folder" then another subfolder called "Sabots" and then create a ShortCut in that subfolder called "Sabots + Bullets Diameters from KingofCoins". Also save the .jpg file to your file system as the same Name that kingofCoins did. this keeps you organized for hunting and shooting.

That may be some good information. But having a background in quality I am wondering how many sabots and bullets were measured? What was the variation between the min and max of each component? What was the repeatability of the measuring equipment used?
This may be nothing more than a 'general rule' simply because the amount of variables involved.
I'm not knocking it and appreciate the effort. But I would like to see more explaination of the recorded data.

I kind of agree with you there bronko. When it comes to one-thousandth of an inch, the quality and type of measuring instrument and the skill of the operator come into play big time. Especially on something like plastic. You should see my efforts with a micrometer. You would laugh.

Even so, it's interesting and useful info.

I just saved it to my pics enlarged and printed much easier for me

I do not think Dan's efforts were meant to be an exact science. It was to find a general difference in the diameters. It all started out in his seach for the right sabot for his gun - he was struggling getting any to load.

I offered some suggestions and then sent him a few sabots. Later after he had complied the information on the few sabots i sent - he/we decided to measure all the different sabots I had on hand. I sentat least 3 sabots each type shown on the chart and some of the different bullets.

Generally from the the information I have from my own measurements and the measurments completed on MM web site - these measurementsmatch up pretty well with the measurments written up in Dan's spreadsheet.

I personally do not know Dan's ability to work a 'mic' or what 'mic' he may have used - but from the information I have and my personal experience with these sabots - I have to say the sheet looksreally close.

I am assuming he used the same bullet in all measurements and I am assuming he used very accurate calipers.
I assume he measured at the mid-section of the sabot, not the bottom and not the top.
I assume that if he repeated these measurements by placing little stickers on the bottom of the sabots with the sabot name, and picking them out of a box blindfolded and measuring them that he would get the same measurement.
I assume that he would NOT squeeze the caliper super tight, but all measurements would be "snug", i.e. get to "touching" and then 1/5 turn past "touching" (it may not be 1/5 turn it may only be 1/10 or something like that).
I assume if he repeated his experiment using theseprocedures, that he would getvery near the same results. Mike, Please email me the spreadsheet, chap@the-gleasons.com, I have some Nosler Partition HG 300g .451 diameter and I have most of these sabots. I also have a Cabelas digital caliper, so I can repeat the experiment, therefore we have a "multi-site clinical trial of sabot thickness". We can of course go the whole 9 yards and do an designed experiment, but that is way beyond our need for scientific validity, to me relative differences is sabots is what is needed. I.E thinnest are ....
next thinnest are....
next thinnest are
...
Thickest are....
Sorta gets at this:

I think if that were done with SW,Nosler, Speer Gold Dot, Barnes MZ, BarnesTMZ,Barnes 45843. We would have some good info for various "bullet user groups".
