Magazine problemsPosted by jpf_11386 on April 25, 2015 at 3:56 am
I recently got a tikka t3 ctr jrtc316 .308, after shooting today every shot when it got below 5 rounds, (after fully loaded 10 rounds) every shot it would bis lodge the magazine. Can't figure out what's the problem and have any one else had the same problem. Thanks for all the advise

Same thing happened with my CTR308 gun first when I got it. Under recoil it would dislodge the mag with hot loads…
There is a problem with the design of the release, the angled part of the release pin that goes into the
Mag wall is cut flat so its at an angle for the quick release…great for dumping/changing a mag but bad if the release spring does not hold everything firm under recoil. The spring is not strong enough with the current design and seating position. Its a flaw only surfacing on the 308 guns from what I have heard or seen so far.
The fix:…get a flat screw driver and insert into the mag slot as per the picture. Apply downward pressure, just enough to raise the top lip on the opening, at the same time this indents the button edge of the slot. This creates a better seating position for the release pin to sit a little further into the mag slot and it puts more pressure on the release when the mag is inserted into the gun. You can actually feel the difference after the fix…no more sloppy movement of the mag when inserted into the gun.
Try it…it will cure the problem.

Thanks Dog Down, Have You Had Any Issues With Your Rifle Not Chambering different ammo. I don't have any reloading equipment so I stuck with buying all ammo. It wont chamber Hornady match 168,only ammo I shot that never had one bullet issue was federal 150, but had Chambering issues with fiocchi 150 not all would fit. Its not hitting the rifling cuz the bullet don't have the grooves in it if it was.

The only ammo I had issues with was a box of federal GM 168gr match…not sure what was going on but I think it was more a sizing / shoulder issue with the brass versus length. I have not had any other issues with factory ammo, including Hornady 168….I actually load a lot of 168amax for my gun and it shoots very well.
Best factory ammo I've shot is Nosler 155gr Match…shot 3 shot 100yrd groups you could cover with a dime.
Very consistent from box to box. Give it a try if you haven't already.

Apologies for hijacking the thread but I didn't want to start a new one on the subject of magazine problems…
Lately I'm having issues with my .308 T3 lite. To start off with the rifle seemed to function perfectly, action felt very nice, fed bullets smoothly and shot very accurately. It's still very new, only fired 40 or so rounds but last time I had it out it developed a feeding problem. Upon operating the bolt it would either not pick up a bullet or it would pick one up and feed it so far before jamming. It does this with any of the 3 types of bullets I have tried. At first I was thinking it was a magazine issue but now I'm not so sure as I've noticed the magazine does not seem to readily click into place and when it does there seems to be some upward movement in it. I'm going to test another magazine when I get my hands on one and see if it makes a difference before I look at possible warranty repair etc but I was curious if anyone else has come across this problem?

Hi mack, My first thought is that there might be some foreign body in the bottom metal (plastic) or magazine release mechanism. 2nd, is there noticable wear on either the release or mag? That about uses up my thoughts on the matter. Good luck

Make sure the rounds are pushed all the way to the back of the magazine when you put them in , last time I was at the range my started not to feed right from my AI magazine it turned out to be my fault and being lazy and not making sure the rounds were pushed to the back , I think it was because I was shooting with some people I hadn't shot with before and had half an eye on them to make sure they wasn't doing anything unsafe

Thanks for the tip Dog Down! That's saved me a trip back to the gun shop with my rifle.

Glad to hear it worked for you as well.
Its just a small flaw in the way the release and box mag work together. Not enough setting depth and pressure on the spring release.
I'm sure it will be fixed on future rifles if it becomes a common problem, but I've had no issues with my rifle since I did this simple mod to the mag. Report back and let us know if it cures the problem after you get a few rounds down range…

I'm not long back from the range after modifying the magazine. Unfortunately I don't seem to have given it enough, as I still had issues with some loads.
I tried giving it a bit more, but to start with I thought I'd ruined it as I couldn't get the catch to seat at all. After taking the magazine on and off a few times though, it now seems to be working fine.
Next trip to the range will hopefully be without any magazine issues!

I have a ctr but I didnt experience the problem yet. Sadly the release lever follow the inertia direction, so maybe a indentation in the top of the lever will help with a stronger spring.
Anybody has disassembled the lever? maybe other commercial strong spring would be used before put the screwdriver.

I have a CTR in .308 and have the same issue shooting 168gr fed GMM .. im going to try the above fix see if it helps..

These guys stole my fix…lol…but its good video for anyone having the same issue with mags unseating themselves and it only adds credibility to the fix I came up with and the design flaw I pointed out in the magazine when the rifles first came to market.
