Yeah, Pat; she has a cool James Bond thwump to her! I wish I could get some numbers, though. I'm dead in the water with my Chairgun until I do.
I'll get 'er figured out. She does have a noticeable kick that my Impact did not have, so maybe that's a contributing factor. It's fun getting all this stuff sorted out though.
Right now, without actual Chrony and empirical BC numbers, my Chairgun is set at a zero of 41.3 yards, a kill zone of 1/2", and a BC of 0.535. That's pretty darn close to empirical numbers I suspect. I'm seeing a pellet drop of 14.58" at 100 yards. That's a lot more than your storied .30 cal, but only about half the drop of my Impact. Sure, higher velocity will produce a flatter trajectory, but a given ballistic impact energy is still that particular ballistic impact energy no matter how it gets there, right?
I no longer have any air guns other than my RAW (except for my Umarex Colt Peacemaker.177 BB pistol). I guess I could throw some BBs across my Chrony.
lol. I installed an LED lighting system on it and it worked fine with my other air rifles (.22, .25 & .30), but it's actin' squirrely with my RAW .357.
I have my set-up dialed-in just right now; getting valid reads each shot. That's a nice rig you got there!"John_in_Ma"This is my indoor setup:
When outside I make sure the lighting conditions are the same for each sensor. As in the whole unit in the sun, or in the shade but not in between. If you have florescent bulbs as most do for ambient light turn them off as that is what is interfering with your chrony.
