Crosman 140 design
I’ve recently resealed one of these and was struck what an elegant design the self resetting valve is
On the other hand, the fiddly loading arrangement and poor sights are a bit of an afterthought , and the trigger is only so so, so I don’t think it’s up there with the greatest crosman designs ever
The thing that really struck me was how inefficient pumping is. Obviously with these there is a concern about keeping the power under the limit so I put in a ludicrous 20 pumps to chrono it. Just under our limit. On the one hand phew, on the other wow that’s a lot of work for a result that a springer will give on one compression. 6 pumps, not a small number, gave only about 6ftlbs. It is very consistent though.
(Incidentally, in all the discussions I’ve seen about keeping the power down on these one thing I have never seen tried is using a smaller tp. I suspect that is what is keeping this one legal (hooray, though I’m also going to reduce the valve volume for added security). I may do some experiments.
Morally flawed
