Today it's gorgeous outside so I did some shooting. I started pellet and scew torque testing with my Hw50. Then I broke out my big dog Weihrauch. My Hw95. It was my first Weihrauch.
All targets are 5 shots at 25 yards. The numbers are AVG velocity- Extreme spread- Standard deviation respectively.
I started with Air arms 8.4 which are made by JSB in a single JSB die. The first group is not great, but that's fresh off the rack. Besides the flyer on #3 the rest were good by me.
Next two are regular JSB 8.44 Exacts that will come from multiple dies. This tin and the other 9 that I bought at the same time print poorly in my other guns as well. The generic unsized JSBs tend to run small and comparatively inconsistently sized. This is why I don't buy more than ten tins of regular JSBs. The JSB specific sized tins like 4.53s are better.
The next two were FX 8.4 which JSB also makes. I suspect these are single die packaged as well. Very uniform fit. Good accuracy and top energy.
Next up was FX 10.3s. I don't normally shoot heavy pellets in my springers because they generally aren't efficient and can be tough on springs. I tried these 10.3s because so many people have had good results with the JSB (and rebrands)10.3s. The first group blew my mind. The next three were good as well.
Next up was H&N FFTs 4.52. These started fast and continually slowed with shot count. This is typical of running H&Ns on a barrel seasoned with JSB lead. Notice the wide Extreme spread and low energy. The velocity and energy eventually stabilizes but always lower than comparable 177 JSB pellets. Except for the third group accuracy was good. That third group might have been me losing concentration. I pulled myself back together on the next group.
To show the effects of barrel seasoning I went back to the FX 10.3s they started slow on the H&N lead and slowly picked up velocity as they seasoned the bore with their own lead. Notice the increased energy and tighter extreme spread on the second ten shot string. These groups were good again. I'll have to pick up more of these 10.3s and do some actual BC testing on them. The way they hit the spinners harder than the 8.44s at 35 yards I suspect they have a considerably better BC.
That's it. I'm so glad the weather finally broke. Friday morning it was -1f and didn't break 32f all day. Yesterday was 24f in the morning and 70f and sunny in the afternoon. Crazy. It's good to be outside and shooting again.
