There have been a few of you expressing frustration over the T3 .223 mag length being a limitation as far as shooting longer bullets such as the 75 and 80gr amax.
I had posted this info in another thread in response to a question but was not easy to dig up with search function, so I think it deserves it's own thread.
Here's what I have done to my mag. I did this last year, and since then I have shot over 400 rounds of 80 gr amax loaded to 2.410 COAL. Every one of those rounds has fed flawlessly the way you would expect a tikka to feed.
I melted down some thermoplastic pellets I got from Princess Auto and poured that into the rear of the mag to from a block. Push the block out with a punch through the hole in the top.
Then cut away the offending piece and also cut back the center tab in the lower cap. I did this with a hack saw blade that I ground on one side (to remove the set from the teeth) so I would not gouge the sides of the mag.
The spring needs to be epoxied to the lower cap as far back as possible or else your ammo will sit so 'nose high' that the bolt won't pick it up.
Grind down the new block evenly to suit the required OAL.
I lengthened the follower with a piece of spring steel bent up and fit under the follower spring.
As I said, I've never had any issues with loading all 6 rounds and feeding is flawless. I was little scary chopping up a $100 mag but works like a charm.
