After getting everything going again, and ready to start the chrony, I found the pad I took all my Mrod notes on when I first got it.
Even with the offering of a fresh battery, the chrony refused to give up meaniful numbers. I have it down to lighting or anagle across the device. a 3000 psi fill gave me 48 shots, 13 of which gave a chrony reading
Guest apperance this evening was my Android running to noise meter apps. One program average 75 db, and the"high noise" was from 65 to 81 db. The other pgram agreed, but put the high number at 91 db.
8 shotsa of Beeman Wadcutters, no chrony data, starting fill 3100. I used the guage on the pump to fill to 3000. Gun gauge shows 3100 to start then to 2800
8 shots Exact Jumbo RS 13,43. no chrony, fill 2800 to ~2450
another 8 of the above, but got 671.9 and 684.2. mabye I didnt let the chrony warm up enough....
8 poly tipped Predators, gave 650.9, 718.8 and 721.4. fill was 2450, but I got distracked trying to get the chrony to cathc something I didnt record the next few fill numbers.....
8 Beerman Bearcubs gave 649.7, 640.3,652,4, no fill data
8 Beeman lasers gave 673.2, 669,9, 661,5, and her I beleive is the threshold of getting louder, 652.9 and 642.9. Had I bothered with a couple more shots, I think we'd have seen much more fall off for the next couple of shots. Fill on those was 1900 to 1500
I should the note the fact that when the gun made the shot at 652.9, it was a differenent sound. You could hear the valve making this loonnnngggg flatuent sound trhing to get enoughair out to drive the pel. I also believe, accoridn the very sketchiy evidence, that the other end of the shot string was valve lock.
So 24 to 36 shots, and this is a stock gun, nothings been adjusted.
