Bonus! I know that I said only one more in this line but I wanted to know something else while I started testing. My son has a Crossman 760 that I was curious how it compared to what I was doing.
The 760 is to prototypical first air rifle. It is affordable and ubiquitous. Most people I knew had one growing up. It can fire BBs or pellets and pumps from 1 to 10 pumps for variable power. Think of it as a value proposition, it is the most bang for the buck.
As all youth’s air rifles do, this particular one has a history. My wife and son bought it at an auction for the private school my kids were attending years ago. They paid probably double what it was worth but they won. My son was very excited at the time. However, it has mostly sat in the corner since the initial outing at the range. Here is the data that I found.
| 760 | 1000 | |
| 1 | 579 | 775 |
| 2 | 544 | 781 |
| 3 | 540 | 779 |
| 4 | 542 | 781 |
| 5 | 549 | 771 |
| 6 | 541 | 772 |
| 7 | 529 | 774 |
| 8 | 539 | 773 |
| 9 | 552 | 777 |
| 10 | 554 | 777 |
| Average | 546 +/- 40 | 776 +/-11 |
I was surprised to see that the 760 is significantly less powerful than the 1000. This was a new pellet, the Crossman 7.4 grain wadcutter, ten pumps each measuring the muzzle velocity. The data for the 1000 is part of the new data set I am doing in my number of pumps vs. velocity analysis coming next week.
The boxes are long gone. I really don’t know what the published velocity is supposed to be. According to today’s literature the velocity is 350-700 fps for the 760 and 750-1000 fps for the 1000. Those numbers are going to be subject to the weight of the pellet as you have seen from my previous data.
I actually have one more BB gun to look at which I will do in a couple weeks. I haven’t done any testing with BBs but since I was checking the catalog of performance, I was curious. I will talk all about that then.
End Your Programming Routine: I have to say, the 760 is much easier to pump than the 1000. I have a feeling that the longer forearm on the 1000 is an indicator that the air chamber is bigger, hence how to get more velocity. I am much preferring my break barrel spring air rifle to pumping 10 times to get similar velocity. But, for a kid this is a fantasy come true.
