What’s the difference between the short and long caliber Tikka chassis?

Most other actions on the market offer two different sizes to accommodate the different lengths of ammunition.  Tikka decided to make one medium action with a size in between what a short and long action would be.

To work with one size action, they shim the backside of their magazines to allow for shorter sized cartridges.  

The only difference with the chassis is the size of the magazine well. For a .223, .308, or 6.5 Creedmoor you will need to select a short caliber so that you can use .223 or .308 AICS style magazines.

For .300WM, 6.5x55, or 30.06 you would need to select a long caliber. But because it’s not as long as a standard long action rifle, we had to produce a custom size magazine to reliably feed, they are listed on our website as the Long Action 3.560” length.

    Just to clarify a bit more on this question...

    I own a Tikka T3x CTR in 6.5 creedmore.  I would need to purchase a short action chassis (LSS Gen2 in my case)to fit my rifle.  

    As far as magazines go, I could use any AICS style magazine with the short action MDT.

    Is this correct?

    Yes, you will need a short action chassis. Yes, most AICS pattern magazines will work without issue. The only exception is the Magpul 7.62 AC P-Mag which is optimized for a Remington 700.
