Good morning,
I'm trying to learn more about the new Panthera and would appreciate comments from current Panthera owners on the data I've compiled to date. My rifle is a 700 cm in .22.
To get started, I tested the rifle to find the muzzle velocity plateau for several regulator settings and a range of hammer settings for each reg setting. Testing was done from the bench with the rifle tethered at 230 BAR. For each reg setting, the hammer setting started at 2.5 on the Micro which was then increased in 5-click increments until max mv was achieved. The first tests were all done with Patriot .218 34 grain slugs.
138 BAR max mv was 965 fps at 3+5 hammer
145 BAR max mv was 969 fps at 3+10 hammer
150 BAR max mv was 988 fps at 3+15 hammer
155 BAR max mv was 1001 fps at 3+30 hammer
160 BAR was mv was 1011 fps at 3+35 hammer
The second test used H&N .218 33 grain slugs at 160 BAR. Max mv was 1010 fps at 3+20 hammer.
The third test used ZAN .218 33 grain slugs at 160 BAR. Max mv was 1024 fps at 3+30 hammer.
My first question is, do these results appear correct for an properly functioning out-of-the box 700 cm .22 Panthera?
The answers are important because I almost returned this rifle due to perceived problems in both the high pressure and regulated air systems.
Thanks
