 Hey guys, it's Kevin. Today we're going to talk about the Benjamin Bulldog 357. So we spend $700 for our PCP rifle. Do we need to actually spend another $400 or $600 for air pump? Some electric air pump runs to $1000. Today we're going to use a hand pump or we call it a foot pump from Amazon and we do it by hand. We pump an empty bulldog from zero to 3000 psi. I'll put the link to the pump to the description section below. The pump came in pretty much assembled. Only thing I need to put it on it is the handle and so there are two screws. It looks good. Connect to the air hose super easy and you can see the air pressure is deadly zero. Turn this knob clockwise to close the air release valve. I'll do a group of 20 so every 20 I stop and record data. I write down the pressure, the time, take me to do the 20 and how I feel. First 100 and 200 pushes, I feel nothing. It just feel like a regular air pump and you'll pump air into a basketball and you can see I just used my arm. I don't feel anything. I use one foot step on the paddle. Later on I feel a little bit of resistance so I do one foot for 10 and another foot for 10 and then it become harder. I just and then I just use my body and bend my knee. If I finish 300 this will start 400. Definitely you'll need some leg. You'll see whole body to push. My leg is not sore. It just like start feeling my leg so maybe feel real good. I'm not pumped up, not tired at all. Okay let's do another 20. Not tired. Seven, eight, ten. Okay that's 20. So when you're shooting you're probably going to go between 2000 to 3000 level and you're gonna have 10 shots. So this is what you're going to do. You're going to bend your knees and use your body weight. It's not that hard. So you can see even it's harder and the time it takes, every time it only takes maybe five, six more seconds. So when we remove the pump we need to release the air. I made a graph of number of pushes and the air pressure. So you can see if we drop to 2000 and we got one, two, three, four, five, six. So we got to do six group of push to get it full. This time increase when we do more of those 20 pushes. You can see the time does increase. So you'll do 40 seconds a group and do six groups. It's totally doable. So for the use of this gun it's totally doable if you only have a hand pump. You don't need to really buy the electric pump. I hope you enjoyed this video.
