THE-SHOOTIST Anyone chubbin' like me for this?
mailmanmike Since Monday! That's more than 4 hours though, so according to those cialis ads I should see my doctor.
tlane77 I think for a non-chemical chubby it's 6 hours before its time to see a doctor. So you should be good for another couple hours.
splattttttt I wasn't goin to google "chubbin" because I assumed it had to do with fat. The lard type, not the fun stuff. But what ever feelings Jeff's experiencing, then they must be of the fun like stuff...

I did quick little test with my s6.5 today, using a pure energy 13/3000 filled to 2500 psi, shooting DXS rec sport at around 275 +/- 15 (horrible paint), out of a 16" redz pepperstick .687, i got 145 usable shots before it vented down the barrel because of no pressure in the tank.

I worked it out to about 17.20 psi per shot with that set up, the reg was left at the factory setting, and the ivg was one turn in from the factory setting.

One thing ive noticed about the s6.5 is it shoots very deep into the tank, there is no real drop off of velocity until maybe the last 2 shots, but even then those two are still at usable velocity.

That's pretty normal. I/m thinking the most you would ever expect is 170-200.

Here's an interesting tidbit:
When I first received my T2 some six or so months ago, my first order of business was to sweetspot the reg, and I found that I was shooting 275 fps (field limit: 280) at 205 psi with the IVG backed all the way out. Increasing the reg's output pressure from there only further increased the velocity, until it started to decrease around the 320 psi mark (I can pull out my chrono and reg tester at some point, and chart this bellcurve, if anyone is interested). Since I already had the IVG backed all the way out, I parked the reg at the 205 psi that allowed me to shoot 275 fps.

It performed quite well at that pressure, and was plenty consistent and efficient... up until this past Saturday.

I suppose maybe I've hit a certain break-in threshold with the springs, because all of a sudden the valve decided it did not like running at that pressure. It would hiss a bit after shots before closing, or even stay open and vent until I re-cocked the gun. As a result, my efficiency tanked. Between games, I hiked up the reg's output pressure to the point where my velocity started to fall (on the back side of the bell curve), and chronoed in at 275 fps again. For what it's worth, I checked the output on my reg tester and I was at 335 psi. Shot a hopper at the chrono station and played one more game with the T2 before deciding to use my Viking a bit, and efficiency was right back where it should be.

Just felt like throwing that out there for anyone who may be looking to maximize their efficiency by sweetspotting their reg. I'm sure other peoples' results may vary, but in my case, velocity very clearly demonstrates a bell curve as regulator pressure is increased. Given my experience with spring break-in, it seems the best option for long-term reliability is to set the pressure on the back side of the velocity bell curve (if your springs don't allow you to set it at the peak).

this weekend
i grabbed my s6, and my 13ci ninja
and made 2 runs for efficency
first was 205 shots
2nd was 212 shots
after that shot the velocity way below my 275 mark,
and 2 shots later valve blew becouse of to less pressure to close

I've seen this happen so often with CCM's snipers that... I'm starting to get the feeling the CCM regs may be suffering from some type of tinsel strength issue.
Maybe the walls on the regs are too thin, or the aluminum they're made from can't handle the pressure.

Just to clarify, I don't have any reason to believe I have any issues with my reg. It's more likely a matter of the valve spring breaking in just slightly and no longer happily closing the valve at 205 psi operating pressure. I've run the CCM reg on my reg tester enough times to have full confidence in the consistency of the reg. Consistency with paint remains +/- 2 or so over the chrono.

I will say I have been nothing but impressed by my t2 efficiency. I used a 13ci tank for the first time this weekend. I shot a full pod, and a very full winchester - and I was still borrowing paint from people. Next time I am at the field I will count every ball I load, but 180-200 rounds to me is fantastic off of the small tank...

*Shooting a fresh box of Allstar, using 679 freak insert on a DW barrel. Did I mention the tank has a leak? I would guess it was around 2500/2700 because the 3k was a hot fill and the needle dropped before I even started shooting. (not sure how bad the tank leak is, but we have filled it, brought it home to find the next morning it is at zero... Just wont hold a fill, so much for brand new)

but its outputting the same psi

yeah i noticed that when i use a spring in the middle of the CCM and a Yellow valve spring i get a quieter more efficient gun tuning for a light quiet pump stroke
