I don't understand such calculations at all. Like dyslexia, I have something with calculations. I don't understand them, and I never will. It's called dyscalculia. Meters per second is something I can imagine. Feet per second is a lot harder. My question is: Is the version on the website of Umarex the 16.5 version or the 7.5 version. _________________ BIG GAP   Posted: Thu May 31, 2007 3:03 pm Alstone Moderator & Site Supporter Joined: 01 Mar 2007 Posts: 4139 Location: Linconshire, ENGLAND 16.5 Joule = 12.16 fpe, so if your Airmagnum 850 puts out 12.16 fpe then it is not standard, It's been modded, am I right.

I think it was 12.5 joule... I will check right away. Edit: I have checked with the seller. I own the 5.5 Import version, which is 16.5 joule. It's also been modded, but that has nothing to do with the CO2 flow or anything. Only a trigger tune and a different airsource "sprocket". (Is it called a sprocket? I don't know, it's to late already) _________________ BIG GAP   Posted: Thu May 31, 2007 3:45 pm AirGunEric Site Admin Joined: 20 Jan 2007 Posts: 6908 Location: "Out There" broommaster2000 wrote: But how do I convert Joule to Fps? Follow the link I posted- find "joules" about the middle of that chart- type in the number of joules you want to convert- and the chart will fill in ALL the other energy units that it lists. For example, 1 Joule is 0.73756 FPE. It's a very handy site. If you go near the top of the page and Click on "Metric Conversion Chart" it will list all sorts of different conversions- not just energy units like on the page that is linked directly. _________________ ` I'd say "I care."

In other words, I can not compare them or anything. It doesn't convert to what I want to know. How many FPS or MPS does my gurn do... It's supposedly around 220 MPS. It's also 16.5 Joule. I have no clue how to calculate such things. They are like chinese to me. _________________ BIG GAP   Posted: Thu May 31, 2007 4:37 pm Alstone Moderator & Site Supporter Joined: 01 Mar 2007 Posts: 4139 Location: Linconshire, ENGLAND If your Airmagnum does 220mps then that equals 715fps, so you must have a modifed Airmagnum 850   Posted: Fri Jun 01, 2007 1:55 am broommaster2000 Moderator Joined: 10 Mar 2007 Posts: 5714 Location: City of Groningen, Groningen, The Netherlands As I said, it's the 16.5 Joule Import version. Nothing else has been modded. I bet the one on the website is the 7.5 Joule version. _________________ BIG GAP   Posted: Fri Jun 01, 2007 2:50 am Alstone Moderator & Site Supporter Joined: 01 Mar 2007 Posts: 4139 Location: Linconshire, ENGLAND Hi Broommaster the Airmagnum on the Umarex site appeares to be the 12 Joule version so yours must be a 16.5 joule model imported into Holland. AL   Posted: Fri Jun 01, 2007 10:29 am broommaster2000 Moderator Joined: 10 Mar 2007 Posts: 5714 Location: City of Groningen, Groningen, The Netherlands Right. So yes, I have the al-mighty 16.5 joule import version, as I stated before. Thanks everyone. _________________ BIG GAP New Winchester     Air Gun Home Forum Index » Rifles You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum All times are GMT - 5 Hours   Page 2 of 2   Goto page Previous  1, 2 All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First  Select a forum Main Forums----------------AirGunHome Q&AGeneral Air Gun Questions and TopicsPicture GalleryTarget Shooting: Casual, Fun and CompetitionHunting, Pest Control, Varminting People/Events/Airgun Issue Discussion----------------Introduce YourselfThe BS TopicClubs/Events/Regional/Political Airgun Issues Maintenance, Modification and Reviews----------------RiflesPistolsAntique, Collector and Novelty AirgunsBB GunsPellets/AmmoOpticsAccessoriesAirgun Smithing Buy, Sell or Trade Forums----------------For SaleWant to Buy   Note: If you are seeing "Please enter your username and password to log in."
