Thread: Kimber 84m 6mmCM & 7mm08 - hacking up barrels to fit.

I recently purchased a second hand Kimber 84m with the intention of fitting my tikka 6 creedmoor barrel to fit it. Luckily because i bought 'as good' but it was a .308 16" barrel that was poked in the last 1/2inch from a previous owner leaving the suppressor on and allowing it to rust pitt badly in the bore and on the muzzle thread.

The kimber 84m is a small diameter action allowing me to repurpose other barrel tenons to fit without having to recut the chamber.

Here is the .308 kimber barrel, an unknown 7mm08 barrel (given to me to as a chop up scrapper) and my tikka trueflyte 6mmCM barrel. You can see the different tenon sizes here.


I practiced first on the 7mm08 barrel. All went well with my measurements and only a minor early threading hiccup caused by me not having a gear engaged 100%.
I also chopped the barrel to 19", recrowned and threaded the muzzle to 1/2 x 20.

Re cut tennon to Kimber spec. I also faced off the "feed cone"(?) like a tikka tenon after this pic.



I worked out the boltface to tenon shoulder measurement for the headspace, which turned out good = 0.003" longer than new brass but smaller than my mates tikka fired brass by 0.001".

"Go gage" case in.



"No-go gage" in.



Assembled ready to test shoot.



It shot well with a thrown together load. Scope adjustments between 1st bottom group and also corrected parralax for 2nd top group. 150gr eldx @ 2.8" 2550fps.



All went well for the test so I've pulled that 7mm08 barrel already. Its a spare now.
