WAR Cobra with 500 cc tank
« on: May 16, 2019, 02:15:45 PM »
I ordered a 500 cc tank for my Cobra (and Jim Gaska delivered!), to replace the 350 cc it came with. Although 33% larger in volume than the original, it weighs about 140% more in weight (1.08 vs. 1.43 pounds). That's an extra 4 ounces hanging on the end of the airgun! Aside from the extra weight (the gun already weights too much!), balance is an important attribute, even though I shoot over bags most of the time. Well folks, I was pleasantly surprised! That little bit of extra weight hanging out there towards the end, actually helped, rather than hindered, off-hand shooting. The pendulum effect I supposed? But there is another trade off.

After exhaustive tests (only two shot series actually), the gun falls off regulator at about 68 shots depending on the ambient temperature. So now, I should get about 90 shots before that threshold occurs. In my case, that means (on an average day), I won't need to refill until I get back to the home base. I like that idea!

I have an Omega compressor. If you're a fellow Guild member, and you pass through Roswell, NM, I'll fill your portable tank as a courtesy.

Nice! I wouldn't know what to do with myself if I had an airgun capable of 90 shots. I'm so used to getting two or three or maybe 10 with any of the big bores. The Marauder will do three or four magazines, but 90? Wowza.
