I've found that most magazines benefit from "tuning ". There are some decent you tube videos. It's generally about 4 things. Smoothing the bottom edges of the feed lips, changing the width of the feed lip openings, altering spring tension and changing the fore and aft amount of spring tension. If I'm understanding correctly, you have 2 problems. 1, the tip of the bullet noses up as you feed the cartridge forward and 2, the bolt passes over the top of the cartridge without contacting the case base. It's a bit hard to diagnose without seeing but it sounds like you have 2 things to fix. The feed lip opening at the aft end is too narrow and doesn't allow the case to sit high enough to allow thebolt to engage enough of the case base. Also, the feed lip space at the front is too wide and allowing the bullet to nose up too soon. You may have too much spring tension in general as well. I'd start by expanding the feed lip space at the aft end. A little goes a long way. Again, I may be misunderstanding your issue. Check out some videos on tuning magazines before doing anything.

Not a Tikka, but I had a full custom rifle that had a similar issue as yours when I first had it back. My gunsmith had a handy tool that he used to tune the lip of the magazine. It was GTG after that. @bill123 has provided you with very useful links that are worth a try. Good luck!

My gunsmith built his own tool, but it is similar to the one in the video.

FWIW, I use the MPA tool. It's expensive but works well.

I had this issue with an earlier t3x (plastic shroud, non-modular stock) in 308. Infrequent but persistent.

I compressed the front of the follower (spring actually but by pressing on the follower) and held it for about 2 minutes. It was the first thing I ever messed on my first firearm. Unfortunately lead me to believe all gun fiddle-fking would be that easy .
Works great and still feeds flawlessly fast or slow.

Possibly a real tight sizing die, which would allow the mag lips to release the forward moving case to early allowing the bullet to tip up and over the chamber entrance. You could J&B the lips and sand tune to correct the early release issue. Maybe easier to only neck size.

I had this only with reloads. Factory loads with heavier bullets fed fine 100% of the time. When I went to lighter (shorter) bullets and started fudging with distance to the lands, only then did I start having fairly consistent feed problems. So I took factory rounds and measured them, made my reloads the exact same length and voila all is good. But that took my load from a 1/2moa to over 1moa just by changing the OAL of the cartridge.

Hi my mags are plastic so the lips cant be tweaked with these tools, And i cant get a metal mag in the uk. Thanks all you guys and stay safe

I had a problem with my tikka CTR mags (2). The last bullet tip in the mag would not be high enough to hit the ramp to chamber. Used the tool to open the front lips of mag a little wider. Solved my problem
