I've search several Tikka forums and this forum and I can't find any definitive information. Does any one know or have a T3 338wm Magazine and see if it could load and feed the 300wsm case? I'd like to seat my heavier bullets out further but restricted by mag length. The bolt stop isn't much of a issue because I could do a simple mod.

Thanks in advance.
 
Provided you have a long action bolt stop, substituting magazines works fine.

The long action bolt stop (the button you push to remove the bolt) can be had from Brownells. Super easy to change.

Substitute mags will lock in but a wsm rounds won't feed from a 300 mag so probably not a 338 mag either. Take apart your factory mag, grind /saw out the stop. Takes about an hour, sharp chisel to finish. Replace the follower with a magnum follower. I think I even had to used the magnum bottom to stack three wsm rounds . This leaves you with spare mag parts, I will make a full length replacement follower to complete the robbed mag when I get a chance. I've done this for a wildcat custom, looks like it all should work, rounds are picked up, and seem to feed. I just haven't been able to fully chamber the round due to the fact I don't have my rifle chambered yet. Currently 7mm rem mag, so long action bolt stop. Waiting on a reamer.
I have tried to use it in a co workers wsm but the bolt stop was in and it wouldn't come back far enough to pick up the round.
Searched for an answer also , couldn't find anything so I've tried this, looks promising. Find magnum mag on EE, bubba away.
 
I just tried to load some 300wsm resized brass in my 338 magazine, they are too tight for the magazine to function, they bow out the sides of the magazine and once you push them all the way in they bind.
 
Thanks guys for the responses. @Kenny_G thanks for the info it is what I wanted to know is if the fatter WSM case would fit and function out of a 338magazine.

Look like I'm going to have to find a WSM mag and bubba the magazine stop to have a longer WSM round to fit. Thanks again to all.
