Having a pest control pellet guns becomes important. This pellet rifle is ideal for pest control and target shooting. The Umarex Fuel, zips 177 caliber non-lead pellets out of the muzzle up to 1200 feet per second. It utilizes a simple, one-stroke cocking mechanism that generates eighteen foot pounds of energy at the muzzle with a lead pellet. The Umarex Fuel comes with fiber optic sights and a 3 by 9 by 32 rifle scope that mounts easily to the Lockdown Rail and its built in fold down bipod makes it great for shooting in the prone position or on a bench. This rifle also incorporates the Umarex Silence Air noise reducer, making it quiet on top of giving it a great look.
Alright everyone! Welcome back to Cody’s Lab. So I just picked up a little $40 pellet gun from the store and apparently this little guy can shoot pellets at 715 feet per second. So today I’m going to use my new chronograph and test that out. And also, something I’ve always wanted to try is to see how fast it shoots when I’ve replaced the air with Helium. So I’m going to be shooting lead pellets through this gun They weight about half a gram each. I’m also going to be shooting indoors because the weather outside is not exactly great. Also, I’m going to be pumping the gun 10 times for each shot That way we’ve got a standard and that is the maximum for this gun. I’m going to shoot 4 shots with each That way we can get sort of a statistical average So here we go Shooting the pure air 3, 2, 1 Chronograph didn’t pick it up.
We’re going to have to fix the lighting. OK so we switched to using incandescent lights because the fluorescent lights were not working with the chronograph. So, I’ve replaced the ring with paper, so lets fire this. Just air, 10 pumps.3, 2, 1 Alright, and we have a number.625 feet per second So this is quite a bit lower than the speed that the gun says in the instructions But that could be because of altitude or variations in the gun type. Let’s run a few more bullets through it so we get an average. So I’ve added this plastic bag covering the gun. This way I can make the atmosphere around the gun Helium That way when I pump it, I’ll be pumping in Helium So, lets see if this holds I’ve already tried it with air, so it aughta hold OK, there we go. Atmosphere of mostly Helium There’s going to be a little bit of oxygen in there But if this speeds up the bullet then we’ll know it’s because of the Helium.
Alright, lets set up that other camera. Let’s see if I can pump this still And load the pellet. Yup, looks good. Make sure I can still pump it.
Kind a awkward there we go. one two three four five six seven eight nine ten all right here we go Helium atmosphere 10 pumps firing in 3 2 1 sounded different. think the velocity is higher not by as much as I thought it might be but it’s a number let’s try this a few more times Wow actually increased a lot that’s just 10 right? How much is it? 733 I think I know what’s going on here so after each shot I’ve been giving it a little bit of extra helium just take into account any diffusion of air into the bag or anything like that and that seems that these velocity of the shells are actually increasing slightly I must be because there’s becoming a greater percentage of helium in here that’s kind of an interesting thing so here’s the velocity numbers for the air and here is for the helium here’s the average for the helium an average from the air you can see the helium is quite a bit more than the air was in fact I worked it out and the energy from the helium was 11.5 joules and from the air 9.1 on average with the max on the helium being 12.5 the max on the air being 9.4 i have to admit that’s not a big difference as I thought it would be but it is still significant so now comes the part where I try to explain how this all works.
