This is in reference to the thread where I asked about data for an old can of Hi-Skor:

Although there isn't any 9mm data for Hi-Skor, I decided to try the Hi-Skor in 9mm anyway. I'm currently doing some 9mm development, and I didn't feel like switching the press over to 45acp, and I really wouldn't have had time to before today's trip to the range.
My reasoning for going ahead with the 9mm: Hi-Skor looks like it loads close to Red Dot, and there are plenty of loads for Red Dot, and 9mm would not have been a popular caliber to reload in the 60s (being more of a European caliber originally), so there's no reason for it to not work well, nor would there have been strong reasons to develop data for it at the time, and it is a fairly high pressure pistol caliber which provides plenty of safety margin (the smaller diameter works in its favor). So to play it safe starting out, I loaded up a pair of cartridges in 9mm (115gr FMJ) at 2.5gr, 2.7gr, 3.0gr, and 3.2gr. At the range - started low, of course, and every one hit the target at 25yds, but fairly spread out. The 3.0gr and 3.2gr grouped OK, but several inches apart. They were very soft, and not a single one fully cycled the action. In fact, only one ejected the spent case, but only a couple of inches.
Some notes: Hi-Skor is surprisingly bulky. It looks like little doughnuts, as the following image shows. It appears that it will meter very well, but I haven't tried running any through the press yet. It burns clean in 9mm, even lightly loaded. It appears that 4.0gr in a 9mm case is about max before it starts to compress, and suspect thats about what it will take to get the action to cycle reliably.
The 9mm case has 5.1gr in it, and the 45acp case has 10.4gr in it.
Here's the can.
