Rebarrling Tikka Mag bolt face

[Semperfi87]

I have a Tikka T3x chambered in 270wsm, I love the 270Wsm cartridge but the options are just not there. With the Mag Boltface I'm looking at Rechambering options? Since the Tikka is a long Action I was thinking the 7mm Remington Mag bc of high BC bullets selection, decent brass etc. 7mm is readily available at most stores looking for opinions on this round. I handload so that is not a problem. Was thinking of a 26in Remington/Sendaro contour barrel with APA gen 2 break. I'm open to other cartridges as well??

You'll have to modify the existing or get a new bolt stop to go from short to long action. Looks like your 270WSM is a .470" bolt face diameter and the 7mmRM is a .540" long action. Bolt faces are crazy expensive on tikkas to get. You could keep your existing bolt face but change the bolt stop and do 270 win, or just change the barrel and do a 308/6.5CM/6CM

I'm skeptical of any "opening up" of the bolt faces, but that's just me.

Pretty sure the base on a 270 WSM is 0.535"

Sure thing. .270 WSM has a magnum bolt face.

I just did a 7saum on a tikka wsm. With the new ARC mags, you could run those and not even need a wsm/saum aics mag. Should be able to get the same speeds as a 7mag.

Doing a 7mag on a tikka will limit your oal. Stick to the wsm calibers.

^^^ what he said. I've been playing with a 300 win for years, oal is the limiting factor.

I turned my 270 wsm t3 into a 65 saum with zero issues. Love the gun

Likewise, sent my T3 270 WSM to GAP and had a Bartlein #3 chambered in 6.5 SAUM. Turned out great

My advice would be 7 saum or 6.5 saum. The only thing keeping me from getting rid of all my non tikka rifles is their COAL limits. If tikka cane out with a longer action, all my LA rifles would be gone and replaced with tikka's in their calibers. 7 saum and 6.5 saum are absolutely hell on critters of all sizes. I believe 7 saum is my next tikka build.

I know this is old, but is the factory mag long enough to get full performance out of the 6.5SAUM? I’m considering one or a 7 SAUM, but I’ve been hesitant with MAG length.

Also, will a 6.5 reamer fully clean up a 6.5 CM chamber?

You can run 338 Lapua mags, long action bolt stop with CDI la bottom metal and load your bullets to the next county

I was asking in reference to factory mags. I don’t want to add all the weight of a DBM and AI mags.
