jpiperson2002, Thank you for the detail reporting. Excellent information!!
I like that you can get the Slash .25 power with the JSB 25 and 34's down to 55/57 fpe. For me, that makes the .25 caliber now much more enticing than the originally published 90J/66fpe by Taipan. Plus, I assume the Power Kits could allow us to go even lower still (or higher).
You documented the issue with the 3D Pellet Seater, and hopefully, Taipan will acknowledge and correct. Possibly more than one Pellet Seater needed.
Can you still seat pellets/slugs individually with appropriate ballpoint pen or golf tee like we do with the Huben's?
Pellets can of course be individually seated to any reasonable depth in the magazine. It's a finicky business without a tool of some kind that loads all of the pellets to the same depth. And it's easy enough to make or find a small pellet press tool like a pen tip or chopstick or something that widens enough to seat a pellet but not enter the magazine any further.
I got spoiled with the very wide pellet variety available in .22 cal. There were always multiple .22 options and most of those seemed to work in most of my airguns. Maybe not very accurately, but they worked.
There are
(probably?) dozens of different varieties of standard commercial .25 cal pellets and slugs out there, plus the specialty houses making slugs. Someone with a .25 cal Slash and a large cache of .25 cal pellets and slugs to test will eventually come up with a recommended list of brands/weights/diameters that work smoothly. I might make another attempt to individually load the Baracudas and Crow Magnums deeper into the magazines to see if that helps.
I haven't checked to see if there is a list of airgun pellet diameters anywhere. The maximum diameter of the solid body of a pellet puts a physical limit on the diameter of the barrel it can use. That's a big deal with slugs since they can't deform as much as pellets, which can have a deep cavity and only one or two narrow bands of physical engagement between the pellet body, the skirt edge, and the barrel.
One nice thing about airguns is that anyone with a chronograph and some time and patience can plot out power curves for different pellets and pressure settings. And a few people also have both the opportunity and the skill to also compare the relative accuracy of different ammo at longer distances likely encountered while hunting.
Forums like this allow everyone with an interest to become an independent researcher and then to post their test results and observations. No grant money or lengthy peer reviews are needed before publishing test results here. As long as they're fair reviews with reasonable tests. The real-world feedback we often see in the forums here really helps the majority of participants who are not able to test things for themselves.
Though I'm not sure if reading the AGN forums usually saves people money in the long run by steering them away from buying airguns they've read about.
Or if reading about new airguns all the time, about how well a new model performs compared to almost anything that has come before.... that it might in fact influence some easily swayed souls to gradually accumulate a small but growing collection of increasingly unique and expensive airguns as time goes on.
