SAM - Maybe I got a bad one!?

I was really excited about the semi-automatic Marauder I had ordered. I thought it was going to be a great second squirrel gun and allow me to take my girlfriends son hunting with me. I had ordered it, a new Hawke scope and a compressor back in December. The SAM was the first to come in from Midway, but it had to sit until the end of last week when I finally got the necessary rings to mount the scope. The wind finally died down yesterday, so I was able to get out and try to zero in the scope.

Unfortunately. zeroing the scope proved impossible. I got almost through the magazines - two with Crossman Premier 14 grain, and one with JSB 18s. (I will get to why I say "almost" later.) It could not be zeroed, because there was no way to tell exactly where it was shooting. My usual course of action is to take a course shot and adjust close. Then I will shoot a group of three, aiming dead center of the bullseye each time and adjust for the center of the group.

The problem was the group. With the exact same point of aim, the first was three inches low and two inches right, the second was 7" to the right and an inch high, and the third was four inches left and about three inches high. So I tried three more, and they, too, were just all over the place. The scope is the Hawke off my Texan, and has never given me any trouble, and the rings were torqued to manufactures specs, so I am doubting the scope or mount is the problem. As stated, I ended up going almost through through three mags and never got a coherent group.

I say "almost" because getting through those mags was a chore. The gun jammed about every third to fourth shot, or the magazine would not advance so it would dry fire. Finally, about halfway through the third mag, the magazine jammed altogether AND NOW IT WONT COME OUT. The gun will cycle and dry fire, but the magazine will not advance or come out of the gun. I pull the charging handle back all the way (which is very difficult to do) but the magazine wont budge. I did notice that when the charging handle is pulled back, it does not go back forward all the way. It stops about 5/8" short and has to be seated back in place by hand.

In any case, I now have a $650 gun with a $250 of scope and rings on it that is totally useless to me as is. Does anyone know if I would send it back to Midway or contact Crossman about this?
 
Got to use the right pellets at the right speed for the accuracy to be good. But, with that size of a group, yours sounds like it is clipping on the moderator or shroud. Check that the shroud and or moderator are tight.

Sounds like it did not like the pellets you were using if it was jamming. Many semi autos are fairly picky about the ammo they will shoot. Others will shoot a variety of pellets well but still they will jam with some. You may be able to push the pellet back into the magazine with a cleaning rod and if you can remove it try a different pellet.
 
Scallen2112, 

That’s a bummer, you should not be having any of those problems especially shooting Crosman 14.3s. I would definitely return it for an exchange, when operating correctly they are a lot of fun and very accurate. Probably got a bad one, there are a few having problems but many are not having problems including me.
 
If you want to clear the jam and remove the magazine, you will need to remove the top portion of the breech. there are 4 screws that hold it to the cylinder. When you remove it be carful you don't loose the transfer port of the 2 o-rings that seal it. Once you have the barrel and breech free, loosen the 2 grub screws on top of the breech and slide out the barrel. This should free the magazine. Run a cleaning rod down the barrel to clear any lodged pellets and then reassemble. If you aren't comfortable with this, then definitely return it to Midway for refund or exchange.

Mine jammed suing the H&N Sniper Magnums and I had to go through the above procedure to clear the jam and remove the magazine. It sounds like you may have gotten a bad barrel, mine shoots the 14.3 grain Crosman Premier Ultra Domes as well as it does the 16 grain AA Diablos. It's doesn't do well with the JSB Hades, those are all over the place, which is odd, because they shoot good from my regular Mrod. I have ordered some supplies to polish the barrel in the hopes it will tighten my groups some more, but for the most part it's shooting sub 1" groups with most pellets at 40 yards.
 
Your accuracy issues were probably caused by feeding/jamming problem. If it is not feeding right, the tails on the pellets can get damaged. It sounds like you have pellets stuck between barrel and mag, now. You can try to use a cleaning rod to push the pellets back.

I'd return it to Midway, but write the serial number down, and provide it to user "crosman_engineer". I think he is on this forum. The crosman product manager is. Maybe try contacting them prior to boxing up, to see if they have suggestions, or other things they would want you to check.



PS: Paul beat me, and his unjamming steps are better.
 
Are you pushing in your forward assist?


Yes. I saw that on the reviews when I was considering the gun, so made sure I did it on first loading the magazine.

FLGunner - Good info, man. Thanks. But I am not going to try to work on this one with all these problems right out of the box. The only thing I did to it was clean the barrel and mount the scope. I am going to send it back to Midway with the magazine still stuck in it. I also do not believe there is a pellet stuck in there. The magazine it not advancing, but the gun is cycling and shooting air out of the end of the barrel.

For now, I am just going to send it back while I reconsider which gun to purchase. There were a couple of other things I did not like, so may go back to a level or bolt action. The gun is bulky and heavy and, after feeling it, I am not sure I want to lug it around in the woods all day. The trigger is also an issue. I hate it. A 5/8"+ second stage? Come on Crossman!

That's a good idea. I don't intend to try to work on the gun - I shouldn't have to right out of the box - but maybe he can look for it on the return from midway and dissect the problems. If it helps them improve the product, then that would be great.

The bolt in this air rifle does not work like on a bolt action. As John pointed out, it's on a spring, so it does not have the force to fully seat a jammed pellet. The reason the rifle is cycling and air is exiting the barrel is because the pellet is lodged between the magazine and the lead of the barrel, but it's not far enough into the barrel to be in front of the transfer port. The rifle cycles because the bolt is stopping at the jam and not advancing any further. If the pellet is lodged in such a way a cleaning rod will not push it back into the magazine, then the only way to clear it is to cut the pellet in half with a long exact knife, or disassemble it as described above. Personally, I think your plan to return it with the magazine jammed into it is probably the best course of action, since Crosman will eventually received in its jammed condition and can maybe figure out why it's happening.

If you are looking for a quality, affordable, regulated airgun for your girlfriend's son to use while hunting with you, look at the DAR .22. It's a regulated side lever action, it's not as heavy as the SAM, it's shorter and easier to handle in the woods, and they are pretty darn accurate!

Isn't that what the forward assist is for? It is pushing in all the way as well with no resistance.

No, it only puts extra spring pre-load on the pellet to try to seat it fully in the barrel. It does not clear most jams.
 
So I was able to get the magazine out of the gun, but for some reason only after I emptied it of air. There was, indeed, a pellet stuck right inside the barrel, though it seemed like the skirt was all the way in, or at least out past the magazine. It was a bit beat up on the back, but I got it out with my cleaning rod. I cleaned and oiled the bolt with balistol, refilled the gun with air and the magazine with JSB 18s, and took it outside. This time it went through all ten shots without a problem.

I still have to go out and zero the scope, but I am going to go get a new tin of pellets first, in case they were the problem. I've had that tin for a couple years. Seems odd that a crossman gun doesn't like crossman pellets, but it is what it is. I still have a few of the JSB an will be ordering an extra 1,000 or more soon. Hopefully they will give me a group I can work with to zero the scope and then see how she shoots.
 
I am sorry that you are having problems with your SAM. Adding some lube to the pellets and bolt will probably fix this issue. I usually add a drop of lube to the head of the first pellet in the magazine when I start a shooting session. Go easy on the lube as a little goes a long way. I will be interested to see if this also fixes your accuracy issue.

Thank you, but it does not. After getting it un-jammed, I once again cleaned the barrel and bolt with ballistol, leaving a thin layer of lube on the bolt. I tried zeroing it again, one pellet at a time, and actually hit the bullseye with my last shot. Thinking it was good now, I put up a new target. This is the result of two magazines, with the gun in the sled, all aiming directly at the bullseye at 30 yards (my zero range for hunting squirrel). At no time during this travesty did I get a shot that landed anywhere near the last one. One shot is almost off the top of the 9" target, and one clipped the edge of the box the target is on. I have a 30 year old Crossman Pumpmaster that does better than this with iron sights and BBs.

The good news is that it only jammed/failed to advance once during these two magazines.
