Short or long action

[Coxy383]

Looking at putting my tikka T3 .243 into a chassis. But unsure if it's a long or short action. Thinking it's a newbie question so hopefully U gents may be able to help me. Thank you

How long is the magazine? I would contact the manufacturer of the chassis you want and ask them to confirm your rifle will fit it, they will know the screw spacings.

Ok thanks for that will do.

I believe that that all T3's & T3x's are the same size (long actions), they just change the bolt stop & fill the magazine well for the shorter cartridges.

EDIT: I just looked on some of the US forums and apparently Brownell's sell a bolt stop & magazine conversion kit.

For the T3, the .243 falls into the 'Medium' magazine length of the 3 bolt-stops they fit when setting a rifle up, along with the .308 and 7mm-08, etc.

But I know my Rem 700 .308 was deemed a 'Short' action when looking at a chassis system, so I'm leaning towards the .243 being considered 'Short' by the chassis manufacturer.
But the only way to know for sure would be to throw the question to the chassis manufacturer.

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, [.243], .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.

Yer after looking abit more it's going to be cheeper and eaiser just to buy one already in a chassis second hand from used guns. Thanks guys

This is very confusing. I tend to think of my 22250. 243 308 as short action and the only long action I have is my 270

That's correct.

Usually is.
Blokes spend heaps rebarreling, and restocking rifles and it just leaves me scratching my head.

Sometimes yes, tinkerers don't get an improvement for the money. For a few reasons.

But just like playing with cars or fooling with gear in your workshop making something you've dreamed up to make something more suitable for what you're trying to achieve, isn't it great to have a choice if you want it.

Tikka rifles are high quality bits of kit, rate right up there in engineering tolerances and smoothness, but at the end of the day, they are Sako's more affordable line but aren't everyone's cup of tea. Big long actions blocked for small cartridges (unnecessary weight and bulk), blocked plastic single-stack magazines that in most cases seriously restrict you seating projectiles out to sit just off the lands, flexible stocks. So up crops the accessories that people like to play with to make them more personalised and fix the above.
Be a sad time when we can't do that, for those people out there finding ways to tweak things to better suit them.
