I did the fix on both my BX-25 and got two shoot with them a little the other day and out of two full loads apiece I still had the problem 2 or 3 times.

What problem are you having? This will only fix the issue with the follower getting bound up and causing insufficient or improper pressure to be applied. Please ensure the casing is long enough to contact the face of the follower but short enough that it doesn't contact the side of the magazine.

I don't know what to tell ya other than that. It fixed my magazine and I don't think mine is special.

The nose of the bullet not being at the right angle causing the round to get stuck in the mag.

I used a 22 short case and it seemed to fit perfectly. They felt better loading them and I had high hopes but still had the problem.

Brilliant...

Simply identifying the problem and fixing it would have been excellent...

Making the connection that a 22 case would be a perfect fit is absolutely brilliant...

You just motivated me to see if I can drill/tap mine for adjusting screws similar to the TI-25 mag...

I had the problem you fixed once...and only once...and I was sure it was due to the fact that I have a bad habit of not counting rounds and don't quit until a 26th round will not fit...the time I had the problem I attributed it to me forcing all the rounds down with too much pressure...now I am convinced by your findings that was true...in my case the top few rounds returned to a normal angle and fired off but the remaining rounds were jammed in hard and would not come out...each one...down to the last round had to be pried out with a screw driver...

Since then I simply count rounds and have not had it malfunction again...but at the same time I don't use much either...

The bigger drawback for me with bx-25 is the excessive free play when fully seated into the mag well...the amount of slop is ridiculous imo...

For your next task...

How about trouble shooting the problem I have with the TI-25...

When manually charging a round it fails to go into battery...

If I lock the bolt open and install the mag and then release the bolt it will go half-way forward...simply pushing it will not work...at that point I have to pull the bolt back slightly and push forward carefully and sometimes the nose of the bullet gets chewed and has to be ejected...

If I install the mag with bolt closed and rack/release in one swift motion it will chamber the bullet but not go completely into battery...at that point simply pushing it completely closed does the job...

It NEVER fails to feed/chamber/100% closed when cycling during firing...

Look forward to a simple fix soon...

Today would be soon enough...

Yesterday would be better...

Going to fix my bx-25 tonight...!

Strange...

I bottom-out my BX-25, by trying to jam in a 26th round, all the time and don't have any of the above issues.

I must have one of the good ones because it's not uncommon for me to go through 300-500 rounds of bulk ammo without a single failure.

Sorry to read some of you guys are having problems.

Hey buck22,

I just noticed the stamp on your used case. What brand puts the hummingbird on the case?

Buck 22. Thanks for the great tip. Have another question for you. Have you tried your fix with a speed loader like butler creek. Every time I loaded mine with the speed loader, constant jams. When hand loaded, no jams. Could your fix give me the best of both worlds? Speed loading and jam free firing. Just asking.

Great Idea,

I took apart my BX25 mags to clean, I noticed they both were very loose, Last time i shot, I had some problems.

I figured it was because it was dirty, or a worn ejector.

I just upgraded my ejector, I did notice that the Red loading ramp inside the BX25 were both very loose, Like the OP picture, they rattled when you shake the mags.

Next time i am at the range I will pick up some 22 brass to introduce to my Dremel tool.

I will use a very light coat high temp lithium Grease inside the new brass bushing, after it is modded and cleaned.

My BX10 does not rattle but different style Mechanism & loader.

I finally got around to it...what a time consuming pita that was...!!!

Took almost a whole minute...

I hereby officially decree this as being the "buck22 mod"....

MarkB

Agreed! "buck22 mod" it is! Works for me.

It fine folks like you buck that make this a top notch forum.

I still have extensive problems with multiple bx-25s with rounds not rising up...

I like the buck22 mod name . I've got two BX's being deliveried today they just may get the BUCK22 mod. They've been on back order since Feb 2.
I just got the mags and inside was a paper that says we've taken a NEW ANGLE on the 25 rd 10/22 magazine. The feed lips present the cartridges at a 30 degree angle for better feeding. So I guess they've made some changes to cure some ofthe problems mentioned in this thread. We'll see

Hey guys, sorry it took so long for me to reply. Been dealing with some issues outside of the gun community.

At any rate, I'm really not sure that this is a 100% fix. While it did drastically improve the situation, I did have a couple of feed issues using Blazer ammunition. Though I attributed that to the lead bullets.

I see a couple of guys are still having issues with theirs as well. I'm not sure why, other than perhaps there's some variance in the way these mags are made. The point can be proven by the fact that some folks have flawless magazines, and others have issues even after the fix that 99.9% fixed mine.

I wish I had more to tell you but honestly I can't put my hands on any other BX25 magazines to look at them and troubleshoot.

As far as the speedloader, forget it. That thing is a piece of garbage, I broke mine the first time I used it. Returned it, got another, and that one made the magazines jam like crazy. Returned that one as well. Also, it really did not appear to make loading the magazines much faster, considering all the fiddling and whatnot you have to do to make it work right. Just my experience, yours may differ.

While considering possible fixes, a lack of lubrication and/or grit may be the cause of the more extreme issues. I noticed much better performance after lubricating the inside of the casing for this mod. I used some motorcycle chain lube that dries sort-of like wax. It's designed NOT to be sticky so dirt and crud won't hang onto it (since obviously that's bad for a motorcycle chain). It's made by Champion: Champion® 4998I - Chain Lube | O'Reilly Auto Parts

I would imagine any teflon based lubricant would also work.

It's an Aguila Colibri/Super Colibri (Can't remember which it was). I just used that since I had a bunch of empties laying around. Plus the casing was shorter to begin with.

ZommyGun - Your issue with the TI magazine...what's happening is when you move the bolt backward, it's dragging over the top of the waiting round, causing it to dip into the magazine, and thus the tip of the bullet is now at a greater angle, allowing it to overcome the friction on the feed ramp.

Simply polishing/cleaning/both the feed ramp/lip on the magazine should cure that problem for you. Strangely enough, I had a very similar issue with my BX25, smashing the bullets. The fix I originally posted cured it though. Ultimately what makes the most difference is making sure that you smack the magazine every few rounds while loading which allows them to properly seat.

As far as the amount of slop with the magazines, I dealt with that by wrapping a single band of electrical tape around the top of the magazine. It's flexible enough to allow full seating, but yet also allows some expansion which takes up the free space.
