My 500mm in 30 cal arrived today. Bought it from Talon Tunes. Very smooth and good experience. Tony was great to deal with.
Gun came with the reg set 135-140ish. And the Hammer was on max. I haven't touched this tune. Wanted to see what it did out of the box.
Didn't have a lot of time. Scoped it, zeroed it, changed the cocking lever and cheek riser over to the left, put a 300 bar bottle on, and installed a carbon fiber sleeve for the barrel liner. I ran a few mags of Hades pellets and a couple of mags of Hybrids. I ran my LabRadar for all shots.
The Hades were crazy good. Almost same hole accurate. Avg speed was 911.2 fps. Extreme Spread was 10.54 and the standard deviation was only 2.67fps.
Plugged everything into JBM ballistics coefficient calculator and got a bc of 0.033. So, with some tweaking and tuning, the 500mm 30 LOVES pellets.
On to hybrids. While the LabRadar data was good, Avg 904fps, ES of 5 fps, stand dev of only 1.81 !!!, the grouping however was terrible.
I suspect the speed was a little anemic for the hybrids. My 30 cal impact shoots them like lasers around 945fps.
This weekend, weather permitting, I plan on really putting it through its paces. Going to install the 8mm hammer, bump the reg up a bit and dropping the hammer tension and see if I can get a better universal hybrid/pellet tune. My initial opinion is that I'm optimistic that this gun has the potential to become a perfect hunting gun. I'll post up better data and targets soon.
