Never been happy with my caps reload. Mostly used International or Universal, loaded in an STS with a Win209 primer and various wads. Just never pleased with on-field performance (27 yard shooting). Read a great deal about Green Dot, so I decided to give it a try. Many posts extolled the virtues of Green Dot in a Federal Gold Medal hull, so that is the direction I headed. Loaded some up (with oem Fed 12S3 wads) and headed out to the range. I was very pleased with the performance. (Krieghoff fixed choke barrel, 34”, Wilkinson, .036 restriction). I wanted to see if I could improve the performance, so I went in search of additional wads. I kept in mind (as I had always been told) that you must only load wads designed for the Fed non-tapered hulls, as opposed to the tapered STS. But when I research Windjammer wads, I found recipes for using the same wad in both types of hulls, which made no sense to me at all. So I decided assemble some components and take some measurements.
It was my plan to test STS/Green Dot reloads right along with Federal Gold Medal/Green Dot. I was already playing a bit with Remington oem fig8 wads, so I decided to use them. I have also loaded a ton of downrange Spolar windjammer clones, and they are among my favorite, so I added them to the mix. At the Federal end, I bought some oem 12S3 wads and also got some Downrange windjammer style clones (DRHF3). I then took five STS hulls and five Gold Medal hulls and sectioned them for measurement.
So are tapered hulls really tapered? Are straight hulls really straight? The answer is yes…barely. The Federal Gold Medal hull has an ID of .72 throughout. The Remington STS measures .715 at the top, .705 at the middle, and .695 near the base. So it is tapered, but not much. (As a side note, do not use these measurements as gospel, as I’m measuring plastic, which is not susceptible to precise measurement. However, the relative measurement DIFFERENCES should be fairly close).
Now, what about the wads? Is there a significant difference between “straight-hulled” wads and “tapered-hull” wads? For measurement, I recorded two figures for each wad. I measured the OD of the bottom (powder cup) and also measured the OD of the bottom of the shot cup. Results were interesting….
OEM Remington Fig8 – Powder cup .69; Bottom of shot cup .70
DownRange Spolar Windjammer - Powder cup .705; Bottom of shot cup .71
OEM Federal 12S3 – Powder cup .72; Bottom of shot cup .715
DownRange 12S3 Windjammer (DRHF3) - Powder cup .695; Bottom of shot cup .705
Next, I decided to “try” the fit of the wads in the sectioned hulls. Results were again interesting...
First, the Remington oem Fig8 wad in the STS:
Next, the DownRange Spolar Windjammer in the STS:
Next, the Federal oem 12S3 in the Gold Medal:
Finally, the DownRange 12S3 Windjammer (DRHF3) in the Gold Medal:
As you can see, the wads in the STS are a nice tight fit. In fact, the DownRange Spolar Windjammer seems to “seat” best. The “fit” in the Gold Medal could at best be described as sloppy, with the DFHF3 being the worst of the lot. Not sure what all this means, if anything. (Might mean that it’s 21 degrees outside and snowing, so I have nothing to do). Obviously, I have a lot of different loads to pattern and shoot before drawing any conclusions. But I was really surprised at how little taper really existed in the STS shells. I was also really surprised at how “loose” the factory 12S3 is in the Federal hull. And it makes me wonder, other than powder migration, does it make any difference? And if it doesn’t make a difference, then the wads I checked are all about the same, with a very slight taper down to the shot cup. And, does that mean there is really no difference between “straight” wads and “tapered” wads?
