Tikka LA 300 WSM and 212 LRX

[ForestryGypsy]

Hope they do some gel testing at low velocities to see if it is as advertised

Seemed to work well in 10% ordnance gel at 904 yards.

Just watched this video and came here looking for info lol. I have a 300WM tikka I’ve been debating putting a 300 WSM barrel on because the COAL is under 3.5” with that bullet and the WSM so it’ll fit the tikka. The 300WM is knocking on the door of 4” so it knocks the tikka action out of the ability to run it in the 300WM.

This is so cool anyone try this? This is an attractive option for a 300 WSM tikka because all you need is a fast twist barrel with a SAAMI chamber. No custom bullet specific throat. And you'd still be set up to shoot 165s and up in factory or whatever. The problem is the magazine for wsms. You'd have to use either an HCA or a MT magazine or custom dbm and they all have their cons.

Factory Tikka long action magnum mags should work. If not, I think shaving the lips a little would fix it.

Just measured one of mine. Looks like you could bore out a magazine to stretch it to a 3.38" COAL but that is still shorter than any 212 loadings I've seen. Barnes load data is at 3.47" and the Vortex guys mentioned they're at 3.46".

I don't think so, WSMs are too fat. I have read SAUMs will work though. I've tried about every other combination

Mountain Tactical is 3.39 IIRC. So the question is would seating them ~ .07 deeper work? The jump would probably be ok but would the neck still be completely on the .308 section? I think it would.

3.46 is the minimum length to have full neck contact so you’d have .07” neck not being used and that much more bullet in the powder column. Be curious if that is sufficient neck for this size of bullet.

Yeah that wouldn't be ideal. I'm thinking that the 300 SAUM would be the the way to go in a Tikka action.

I don’t think it’s too big of a deal. Just swap in a Red snake bottom metal and a 3.715 aics mag then you’re good up to 3.5”. Already needing a new barrel, probably new stock, and aftermarket magazine.

True but if you went 300 SAUM I think all you need is a new barrel and a long action magazine and bolt stop

There are better bullets out there. I personally would not build a rifle around this bullet. Apex and Cayuga have a better balance of weight and BC. The Apex 194 has a g7 of .357... That's basically better than the 212 LRX, lower recoil higher velocity and better BC. There is no need for a 212 grain copper it's so over kill even 194 is going to penetrate like a freight train.

Most of the barns bullets really don't perform well under 2000 fps sure it " might" expand to 1800 if you hit solid bone going in but there are far better bullets like berger,the hornday eldm to name a few the sierra tmk ect.... also hammer bullets tend to perform much better shooting bother better velocity and better low impact performance over barns....I do like barns but they are a sub 500 yard bullet for the most part .

I liked the way they were bucking wind in the video though…

Weight doesn't cause that though. Velocity and BC do. If a lighter bullet has a better BC, it'll be faster from the same cartridge and have less wind drift at every distance. That 194 apex is a wildly better bullet from a external ballistics standpoint than the 212 LRX. I'd argue it's better terminally to.

This is what I mean. The 212 is a weird stunt by Barnes, not sure why they went this route... Building a rifle around it would be weird too it's just an odd concept.

I've often considered having a Tikka 300 wsm built around the 212 lrx bullet. Converted to use it's LA overall length, I think it could work well but I've not found any reports of anyone's similar efforts. Barnes lists this bullet with an insane BC at .705 and many hand loads achieving more than 2800 fps. Barnes also says this bullet has minimum expansion velocity of 1600 fps, putting that at around 1200 yards (not that I would ever shoot at an animal nearly that far).

This sounds a bit too good to be true. Am I missing something? In case anyone wants to know, the purpose would be improving margin of error for Alaskan moose at extended range. I've done this with TTSX's from 375's and 338's out to 450 yards and they work well but these are getting a bit close to their minimum velocity at around 500 yards and my hunting terrain sometimes doesn't allow getting close. This setup definitely seems superior than those.

I am led to believe this hasn't been tried and reported on since a 1-8 twist is required and these bullets weren't available for a while. But I am curious if anyone has looked more into it and/or give their educated guesses for it's viability.

Im almost done with the build you describe and so is 503 impact sports on you tube.
The loaded rounds iv set up are amazing looking. factory barel sends them keyholeing. I've got a barrel coming from OMR and hope to have it shooting in less than a month. I've been doing some velocity testing and im getting 2980fps out of my friends 26in its a 1/9 and destabilizes around 100yards and has a tail on paper at 70yards. Im looking forward to have it completed soon. don't want to post more info until i can give good result pictures.

On a Tikka, correct? What's your COAL? If it's similar to Barnes' load data of 3.475", how did you get it to fit in the magazine?
