I am having a problem with my SX1. The bolt is staying back and not cycling the second shell. Let me also confess that the problem is likely to have been self induced.
What I did!
I ordered a new HD recoil spring for my SX1. It did not cycle the gun, so after consulting a SX1 expert, it was suggested I open the ports. Gun worked great and cycled fine for many rounds. Then the bolt follower broke, I replaced it. Later the bolt broke, I replaced it. Then the second bolt follower broke, and I replaced it with a HD follower from Bob Baumgart. Please note that the follower and bolt failures could have been from normal wear and tear for the gun was well used when I got it and the parts were scavanged off a very old and beaten up SX1, with the obvious exception of the newest follower purchased from Bob Baumgart.
All was well and good, then the gun would not cycle the second shell. I replaced the recoil spring with another identical new HD spring. The old spring had compressed about three inches, but probably had at leat 10,000 rounds through it and maybe as high as 25,000 rounds (maybe even more). The new spring solved the problem only briefly, about 2,000 rounds, and the gun is now not cycling the second round. I checked the bolt buffer and it is intact.
I have a second barrel which does not have the ports opened and I believe it will work, but it is full choke, which is a little tight for skeet and sporting clays.
I think that there is something else wrong, but I can not pinpoint it. I will be using my untouched barrel from now on, but I am concerned that the gun has failed to cycle so soon after a fresh spring.
Any constructive thoughts will be appreciated on what might be wrong. I do not require being reprimanded for touching the ports because a mal-functioning gun and the expense of repairing it has been more than adequate.
Thanks!
