Gunsmithing Tikka question...

[evilsvt]

Since all of the Tikkas use the same action, does the action need to be modified to feed longer short action cartridges?

All t3's are long action, but feed short action cartridges just fine

i just reread what I typed and it's clear as mud. What I meant to ask was since all T3's are long actions, do they need to be modified when using longer bullets in SA calibers like 6mm CM sat out long. I know remington 700s need to have the feed ramps trimmed up to clear the longer rounds.

I don't see why they would. The bolt throw length is governed by two different bolt stops, and the magazines are reduced by a spacer in the rear of the magazine. If you wanted to use a .223 with really long bullets or your 6mm cm with long bullets, just use a long magazine and a long bolt stop. If you try and load long with short bolt stop and short magazines then yes you would have lots of problems.

If you have a 308 and use the M size mags (they are all the same size just spaces inside), you can buy the long cartridge bolt stop and use the L mags (for the 30-06 7mm mag etc) and seat your bullets out.

Thanks for the info with the bolt stop. Any idea it'll work with the AICS mags since the mags are shorter and I don't know the relationship of the magazine to the action

The AI mag will be the limiting factor to how far out you can seat the bullets. CDI makes the AI compatible bottom metal for the Tikka, but I only know of the 308 mags sized. To do what you are asking, you will have to go back to the std Tikka BM and mags. If there is an aftermarket, long cartridge/bm combo, I have not seen it.
