Condor 308
I’ve been testing my R&L Condor in 308 caliber that I got a couple of weeks ago. I’m using a EtacHPA and a 68/4800 Carbon fiber tank, so it’s a completely different setup than their normal 308.
I first started out testing a 52 grain bullet and saw over 37 to 40 shots on low power wheel setting and starting at 2700psi with speeds from 840fps-860fps-840fps.
I adjusted the PW to a higher setting after the first 20 shots for 8 shots back in the 860fps and turned it back down for 12 more shots between 840 and 860 before dropping to 820fps at 1800psi. I was wasting air when I turned the PW up, so I should try it again without touching it.
I finally was able to get a shooting area set up in my shop over the weekend and after 80 shots at 2500psi to 2000psi to had an idea of how the power wheel and top hat effected the speeds.
3000psi looks good and I may get a nice shot curve at 3200psi.

Available amount of air for the Standard Condor tank is 490 CC
29.90ci x 3000/14.7 = 6102.04 ci /1728 = 3.53 CF = 99,958.468 cc
For my Carbon Fiber tank..
68×3000/14.7 = 13877 ci / 1728 = 8.03 CF = 227,384.278 cc
68×4500/14.7 – 20816 ci / 1728 = 12.05 CF = 341,218.001 cc

One thing that makes my setup different besides the amount of air is that I am using the EtacHPA and the direct amount of the air flow is different.
This should give you an idea of the available space in front of the valve and spring seat. Measurements may not be exact, but as close as I could get them.

One change I did between my two test was to polish the spring seat and add a bevel to the spring seat opening as well.
This image is after removing some material and beveling the edge.

This is after I polished the spring seat.

My next test will be to make a new spring seat that takes up less room in the Etac’s air chamber.
This should either give me the amount of air I need to break 200fpe or slow me down because of the added amount of air needed to fill the chamber up before entering the valve.

That’s another conversation all together because I would suggest a tuned 909, Quackenbush or Haley gun in 45 caliber or larger for big game before buying a recluse even if you want it for small game. I might recommend anything over a recluse if that is what you are considering. I think the power and the size of the hole of the 909 is better if you don’t have a bigbore. Keep in mind they eat air!!
So far I love what I have and I’m very happy with the shot count. The accuracy will tell the rest of the story and what I will be able to shoot.
The 308 matched what I was looking for which was something more than 22cal LR power and lots of shots. I like doing things differently and was looking at using a CF tank for more shots and the EtacHPA helped me make it work. The tank looks big, but the fit is great with the drop of the EtacHPA.
As for why the 308, I have a Quackenbush 458 and I tuned my 22cal QB to make 60fpe over 8 shots and wanted something in between. So I tuned by QB back down to 40 fpe and was going for a Condor in 25 and the 308 came along.
The other reason the 308 won for me was because my State hunting regulations make it where I can’t hunt coyotes with anything larger than a 30 caliber unless deer season is in.
So with the 30 caliber I will be able to hunt squirrels, nutrias, coyotes and head shots on hogs when deer season is not open and I am unable to hunt with my 458.
