Very Nice write up! Tacked!

Interesting. I was about to send my kit back in tomorrow. Now I need to decide whether to try this, or send the kit in.

Update:
Polished it a couple days ago.
Shot it today. Runs great. Thanks. Saved me and Spikes Tactical a headache.

Does this work the same way with the drop in bolt conversion kits?

Thanks for the post…I’m here to tell ya it works, I could not run thru a full mag of Remington’s with out a feed issue or two. I followed boatbod’s instructions and went out for a try, not one issue with the Remington GB rounds.

Ok went back and did the same to my Spikes Conversion, same great results. I did go one step farther on both and polished the rails to a nice mirror finish.

Thanks, very nice write up. I need to do this to mine, as I am having similar problems.

Cool tips, thanks.

Polishing the feed ramp extension on the chamber is a good starting point and you can get to it without pulling the barrel.

Great write up. Thanks for the effort.

I tried this today and tested the kit.
It most definitely improved the gb but it was still only reliable about 50% of the time.
I'm not great at tedious stuff like polishing so i'm going to quit while i'm ahead i don't want to mess it up.........

The kit still seems as reliable as any 22 is going to be with federal bulk pack.
I'm just going to keep testing different brands of ammo that people say work and buy every rnd of it i can get my hands on once it proves reliable.

I've been reading all the posts about how crappy this ammo is: So not being a fool I only bought the bulk pack Federal.

Took my GSG-5 & Spikes ST-22 to the range today, both worked AWSOME with the Federal Bulk. Then a guy wondered over to check out the AR-15 / ST22 and stated he ALWAYS used the REMINGTON Bulk.

I loaded and fired MANY clips of the REMINGTON BULK he had in BOTH guns, and MUCH to my suprise they BOTH feed flawlessly and the REMINGTON shot better groups from the bench @ 25 yards than the FEDERAL..

Going to give them a HARD LOOK... Its hard to find the FEDERAL without paying Cabela's prices ( $20.99 ).

I'm doing this later today. I still cannot get anything but federal to feed with any reliability even after 1500 or more rounds down the pipe.
I have already polished the part of the feed ramp and the bottom of the bolt assembly where it potentially could contact the bolt catch.

But if I can shoot Rem GB's then I don't care if it takes me an afternoon polishing - I'll do it. Every time I try to get my hands on the federal ammo its gone now.
stupid craze has people buying up all the ammo every where I go.

When initially trying to break it in, I percussively chambered the Remington GB's and when I could get them to chamber and fire I had no problems with accuracy.
But what I noticed is many of them would not chamber even being inserted straight into the bore of the conversion. I had this same problem with rounds simply being too
big to fit with Winchester, and some CCI as well. Blazer I could not get a single round to chamber feeding them into the adapter (outside of the weapon) by hand.

I think this is going to be the final step to getting this thing to run reliably.
Good post!

I am merely using the conversion. And I am already post Remington GB's at this point in the drop test.
I set them on the bolt just past the extractor at the typical feed angle and let the recoil spring chamber them.
(Outside of the rifle, on a bench.)

I just got 30 / 30 to feed (pulling randomly from a value pack) THE WHOLE way in to the chamber using this method where before I could get 1/30, IF that to feed.


I had minimal feeding success previous to this even pushing them into the chamber straight with my fingers. This was obviously just a bad chamber adapter.
It was WAY too tight. I knew this, I just thought it would break in after so many rounds. It didn't happen.

I had already taken the tool marks out of the bottom half of the feed ramp. But I was using a polishing stone to do it, couldn't get in tight on the ramp, and was afraid of removing too much material.
So I bought the soft cloth bit you were using and used the side of the bit on the ramp, and plunged it forward on the same angle as the ramp into the chamber. This knocked out some of the edge on the bottom of the chamber / feed ramp area. Then I took the same bit and pressed it directly into the chamber allowing it to open the edges ever so slightly and mirror polish everything smooth. THEN, I took about 20 Q tips and straight rouge and worked the top of the chamber where the nose rides as you mentioned. Then I went over the ENTIRE chamber area lightly about 3-4 times.

I knew it [mine] was extremely tight where even federal ammo wouldn't drop in by hand so I wouldn't recommend doing it this way for the average person. In all honesty I probably should have sent it back to Spikes. But, I honestly felt like this was something I should have done on day 2 of fighting with it. Instead of peckering around with it and putting it off as long as I did.

I'm still in the process of drop testing from various lots of ammo at random to be certain I'm not binding when I drop them in by hand, then at a normal feed angle. So far I've gotten everything to go but Remington Subsonics and CBee22's. I would REALLY like to get the standard Rem Subs to fire with 75% or better consistency. As I was able to get 40% or so before doing anything. And they do have enough energy to cock the hammer so its a matter of taking out any chambering resistance at this point IMO. The federal auto match and bulk pack I still have limited quantities of feeds so well I can literally drop the shell from an inch above the chamber and the weight of the round falling is enough to bottom it out in the chamber. Rounds will actually extract now as well without using a blade to hold the extractor paw tight against the rim while drawing back the bolt.

I think I'm getting some where but I don't want to go much further without testing its operation in the rifle first.


My current problem with the Remmy subs is that it binds on the actual casing and not the nose as you would expect. They almost seem bulged. And I'm not opening a chamber to account for that. I will just try Aguila subs or someone else's instead.

Charging handle latch to stiff?

That's the issue Federal Bulk, I have not seen any locally since January and I stop by many stores at least 2-3 times a week. I get lucky sometimes with ammo but never have with the Federal Bulk, I have one box stashed away, I got to find it and try a few but hate to waste it all till' I can find another stash and stock up.

Anyone know where the Federal Bulk can be found mail order ?
