Brand new Daisy 753 won't shoot

Mine was dependable, never a problem. Try the pump first moving the handle all the way forward, then cock the gun loading it.

Hello.

I've had these rifles get a wayward pellet falling into the action and stop up the works, so put the safety on, open the bolt to the cocked stage and turn the rifle over and see if you can shake out a pellet or two, you might have to take the palm of your hand and smack it like your trying to get ketchup out of a bottle. See if that works.

Shooter II

When I first got it a couple weeks ago, it didn't shoot the first time.  I read instructions carefully, it seemed to require cocking with safety off, pumping with safety on, and be sensititve to the order.  Then I "realized" the bolt hadn't clicked all the way forward.  Eventually I got it working and sighted in.  I was probably wrong about all that, because..

yesterday I shot the first pellet.  Loaded the second and only got a click.  Tried recocking and repumping multiple times, could never get it to fire.  Decided not to leave a pellet in it, so tapped it out with the cleaning rod, pulled the trigger and it fired.  It had pressure but it didn't shoot.  So it doesn't seem to be the pump, and the hammer releases, but the air didn't.  I think.  I'll try some different pellets today and see if one type gets stuck maybe?  I dunno.  

I can send it back, but if it was just a matter of some missing lube somewhere that's going to recur anyway I would try that first.  It's my first SSP rifle.  I've had a P3 for at least 20 maybe 30 years and never any trouble, and so far I'm happy with the new 46M.  

A little more experimentation.  

RWS H Point, RWS Meisterkugeln, JSB Exact Match Diabolo, and Crosman Wadcutter all fired 5 pellets each without a misfire.

Crosman Premier Domes (I had a few left in the cardboard box) had 1 misfire out of 5 pellets.

Modern Crosman Domes in the round tin had 3 misfires out of 3.

All misfires still had pressure and would fire when recocked without pumping again, after I'd carefully removed the pellet of course.  (And of course that meant until I figured that out, I pumped it more than once a few times.)

The Crosman pellets that misfired were noticeably harder to chamber. 

So now I don't know what to think.  I don't think I would have started with Crosman and I had some misfires on unboxing, but I didn't keep track.    

Something wrong with either chamber or bolt that causes incomplete lockup, maybe?  

Take what I say with a grain of salt as I've never touched the model you speak of. But, if I had to guess, here's what I'd say.

That model is a "single-stroke-pneumatic" meaning it will only hold one stroke or pump. If you pump it more, it releases the air pressure from the previous pump and repressurizes with the next pump. So you can't overpressurize it. It is simpler than you might think. There's no inlet valve. The pressurized air is held between the exhaust valve (released on firing) and the pump cup.

Some Crosman pellets are known for being somewhat harder than the norm. Heck, maybe they all are. Add in a little size variation on the less than "premier" pellets and you have bigger, harder pellets that are being pushed by a very mild powerplant. So they just don't budge.

That is my far-from-expert opinion. Your gun is likely fine. It is curious that this problem hasn't really come up before to my knowledge, so maybe your gun is a little on the milder side. Or maybe it's "supply chain issues."

you did the testing, you have the facts

the rifle does not like the Crosman pellets, so feed it what it likes 

the rifle can not be bad if it works on another brand pellet, the why is less important but your testing should be added to a product review so others down the road will have your knowledge to help them avoid the problems you have had  

happy shooting 

tell us what you jammed into it, and we'll tell you why it won't go into battery 🤣 

was it the kabob skewers again? Oh,a Crosman pellet.

I had read that Crosman added antimony to the pellets to make them a bit harder.

Because of the Crosman 600 pistol.

Softer pellets weren't feeding well enough through it.

That may be so.  I had 4 different models of Crosman pellets:  the old Premier Domes in the cardboard 1250 box, the newer "recreational" domes, the hollow points which are pretty much domes, and a plastic box of cheap Crosman Premier wadcutters in 7.4 gr.  

The wadcutters chamber fine and actually shoot pretty well in most of my guns.  The other three don't want to go into battery easily and misfire.
