For .22LR, it's C.O.A.L. that is significant -the case mouth is usually no higher than flush with the bullet O.D.Have you tried different ammo? Sounds like the ammo your using has to long of a case length.

Aha! The plot thickens (that's another way of saying I dunno what's going on). My GUESS is: Provided that these are BX-25s and not "Hot Lips" or some other after-market mags, there is something strange about one of those brands of ammo.Thanks for the replies.
I have tried various ammo and some works better than others. Unfortunately, I have dumped several bulk boxes into an ammo can so I don't know exactly what is what. I will do some testing on ammo that is still in boxes so I can figure this out.
I have 4 mags that I was using and all of them were experiencing the same problem.
By the way, when I emptied the BX-25s I had to us a sharp object to lift the point of the bullet so I could push the shell out. The point was sort of laying down in the mouth of the magazine.
I 'liked' this post in my guise as a retired tech writer. It could use a little proof reading, and a smidgin of rearranging, but it's clear and followable..The problem with the BX25 feed is the spring.
Unlike most magazines that push the follower upwards, the BX25 pulls it upward and causes the follower to torque in the tracking.
This pushes the head of the bullet downwards and it get caught under the metal lips of the feeder.
Easy and Cheap Fix : buy some 3/16 heat shrink tuning from a store that sell electrical supplies.
Take the magazine apart - 2 screws -
You will find 3 parts; metal feeder, follower and a coiled spring.
The spring slides onto a tab that is located on the follower.
Note how loosely the spring sets on this tab .. this is the problem.
Take a cut a piece of heat shrink tubing, place it on the tab and use a hair dryer to shrink it on snug. Do not melt the plastic follower.
Reassemble in the inner pieces. You will notice that tubing acts as a spacer and fills the gap between the spring and follower tab.
The spring should still turn easily on the tab.
Reassemble the magazine and test it out.
