I read lots of threads but i seem to not be able to figure out my problem. My Spike ST-22 will eat Federal, winchester subsonic, winchester 333,555 but it won't cycle Remington Subsonic. Unfortunately, this is the only ammo that I can get easily. What can I do to make it work. Right now, with this ammo, it doesn't close the bolt all the way. It only does it with this ammo...
What do i need to do? Note: I shoot with a suppressor so subsonic ammo is necessary. |

Remington sub sonic won't cycle worth a damn in any semi auto I have. you can try shortening the recoil spring but if I were going to do that, I would have a second spring for all other ammo.
Also, the remington bullet profile is bad for feeding in the Spikes as is it being lead(no copper wash). It will gum the ramp and chamber up pretty quick. Can you hand cycle the rounds ok? Why do you say you have to shoot sub sonic because of the can? Sub sonic ammo is a choice, not a necessity. |

I have used Remington Subsonic in my 10/22, 22/77, mossberg 144, and my DPMS 22lr with no problems too but i want to be able to use it in the Spikes upper. I have polished the feed ramp and the chamber and no change. I tried using a second magazine and no change. The reason for using Remington Subs is because it is the only thing that I have available to me locally.
I hate to cut the spring because the gun works with everything else. |
You need to quit thinking small, meaning, in your area. Order Winchester 555's or Federal Bulk On-Line and in quantity.
Remington's work great in my 10/22's and revolvers. Others who have luck with them feeding through an Atchisson Design conversion are the exception. Probably 1% of the kits may work with it. BTW, Federal Bulk really sucks in my 10/22's Good Luck and I hope you can find some reliable ammo on the web. Spec |

The local Wally world has plenty of that ammo too. I just want to be able to use the Rem Subs so I can shoot quietly. I have tried the CCI and it works, it is just more expensive. The nice thing about Rem Subs is that you can get it almost anywhere... |

Where in NC are you located? You gotta find some different ammo. I have access to some better stuff locally and always pick up good subsonic ammo at the local shows(Charlotte). There is a show in Raleigh, this weekend, If i can find some Non-Rem Subs, i'll stock up. |

The Rem subs don't have much umph to them. Even though it's picking up another round, it may not be producing enough return pressure to seat the round. Spikes has a very step angle on the feed ramp. My Spikes conversion gave me fits. I could never get Rem subs to feed reliably.
Make sure nothing on the conversion is causing excess friction. I've had rails with a slight bend in them. Check all the roll pins also, making sure none are sticking out or rubbing. Are you using a rounded hammer? |

I would think that if it is a FTF, cutting the spring would only worsen the problem. If it is picking up the next round, and failing to seat it completely in teh chamber. Doc Maybe, maybe not. One of the primary reasons for the bolt failing to go fully into battery is the driving bands of the bullet being deformed during feeding. This happens after it hangs up on the sharp transition between the feed ramp and the chamber mouth and the back of the cartridge gets smacked by the bolt. Polishing & reprofiling (as described in the ST22 Tweaks thread) addresses this problem and allows blunter nosed ammo to feed properly. |

There are more pictures in the thread that I linked previously, but here is the important one. Note that you're not reprofiling the ramp, you're smoothing out the transition in the ramp extension which is on the bottom of the barrel.

| just read your post. gets some jb bore compound. use a dremel tool with a conical felt bob on the end. put some jb on the front of the bob and run the felt tip on the inside opening of the bbl. chamber. use a circular motion and use VERY LITTLE PRESSURE. the compound will do the work. pay special attention to the bottom portion of the chamber where the feed ramp meets the chamber. open it up just a little bit. do all of this a little at a time. and try hand feeding a round at diff. times to check round fit. rem ammo( brass ) is a hair wider than others. there was a post on this operation in the spikes industry section. i did this with mine and it will eat any and all ammo. |

I made the feed ramp on the barrel more pronounced and it looks like i fixed the problem. I tried it on full Magazine in the garage with Remington subsonics and it ate all of them up with no FTF or an OOB. It might be a little premature to say it fixed it but i will have to try a couple more mags to see what happens. I hope it still eats all the other brands of ammo.
Another question - Spikes had the barrel nut on tight, more then 60 foot pounds. I didn't see any assemble lube on the threads or what not. How tight are the barrel nuts supposed to be on the 22 barrels and do the threads need any lube? |

How tight are the barrel nuts supposed to be on the 22 barrels and do the threads need any lube? Tight enough not to come undone on their own, and not so tight that you bend the ears on the nut. Yeah, I know that's kinda vague, but if you go about 30ft-lb or so, then line up the nut for the hand guards you should be ok. |
