Back Room / Re: Good morning! Are you up yet? What's your plans for today?« Last post by Madd Hatter on Today at 11:19:08 AM »Good morning GTA! Happy Friday Eve!!! I slept in until nearly 0600… things have been chaotic lately, everywhere around me: work, church, home, family, etc. It’s all good, because I’ve had enough. Topped it off with my birthday yesterday that went to south all day. Ayrabella stayed home from school because we stayed up too late. I’ve had my 2 cups of coffee, but there’s no work this morning and thunderstorms. The girls are still in bed, so I think I’ll turn my ringers down and go back to bed for a couple hours. We’ll see what I might do afterwards, if the office doesn’t come up with something. I’m not complaining, I’m just declaring no more chaos for me. Way past due that I put the monkeys back in their cage… I down even own a monkey.Happy birthday John!🎉🎇🥳🥳 15

I get from this data shows it to be .019 The HAM article shows these pellets having a B.C. rating of .012? I'm using the Pyramid Air Balistics calculator to get the numbers?

PCP/CO2/HPA Air Gun Gates "The Darkside" / Re: Benjamin Fortitude Leak Question« Last post by nervoustrigger on Today at 10:58:20 AM »Usually when a slow leak occurs at high pressure and then eventually stops, it is because of one of two reasons:
1. An O-ring is beginning to extrude. The long-term effect of pressure acting on an O-ring is that it deforms, flattens out, and may eventually push into the small gap in between the parts. If you've ever replaced an O-ring that has little wispy wings hanging off of it, that's extrusion. So at high pressure, the material thins out to the point where a slow leak develops. Then as the pressure falls, the O-ring relaxes a little and seals up again. 2. An O-ring is hardening / becoming brittle. This symptom is especially common with regulators on account of the heating effect which occurs each time it replenishes the plenum, which causes the material to degrade at an accelerated rate. The two most susceptible to it are the one at the small end of the regulator piston, and the one nearby on the pressure adjuster screw (if present). The one on the piston is the one that will cause a leak. A soapy water check of the regulator's atmospheric vent will find it right away. Usually it's a pinhole near the regulator, in which case simply placing clear tape over it will show it without the need for soapy water. Whereas some regulators vent opportunistically through an adjacent threaded connection, in which case soapy water or leak detector fluid is the answer. I hope this helps. 17

Dirt or an impediment would cause the poppet to leak, but it would have leaked at all stages of pressure. If it’s the poppet, I’d burnish it first, the “plastic” portion that sits on the valve seat, by attaching it to a hand drill, using fine grit. Removing the shroud for the balloon test would optimize results. 18
Back Room / Re: Good morning! Are you up yet? What's your plans for today?« Last post by Ronfiveo on Today at 10:20:07 AM »Yesterday my final two shots dropped a good 3" from POA.
I cocked it again and I could hear some hissing and gurgling from around the breech area. I was thinking that I would have to do another rebuild. It hasn't been that long. This morning I tried it out again and the first shot was ok, then when I cocked it the gurgling was back. But after that it seems to be shooting well as usual. I have no idea of why it's so intermittent. If it keeps shooting ok, then fine, but if it continues to be hit or miss (pun intended) then I might have to do another rebuild with changing the O-rings and valve kit. I sure don't want to do that.
