That is affirmative. The model no. ends with R10...also the barrel will have 10” stamped on. Apparently Tikka is phasing out the 300 WSM from their product lines. This is new this year so there are still new 300 win mags out there with the old 11” twist rate.
Yes but it’s kind of a moot point in the 300 win mag with Tikkas short mag box length. Any bullet needing a 10 twist will eat up too much powder capacity. If Tikka would offer the WSM with a 10 twist it would be a perfect candidate to send out for the throat to be extended.
Not a problem....replace the bottom metal and use an AICS mag.
That turned out to be a very expensive mistake on my part….Scrapped my Tikka 300 win mag because of the action length limitation.
Unless you plan to shoot 200 gr or above, low drag bullets with a high BC, you won’t need a 1:10”. The shorter conventional bullets like the Accubond don’t need a faster twist. If you practice and hunt at a higher elevation you probably won’t need a faster twist at all if shooting less than a bullet weight like a 215 Berger.
how long were you loading them? i have a 7rem mag tikka with the aics and i can touch the lands within the mag w/168ablr.
Not very long. The newer Tikka 300 win mag barrel has a long leade to shoot the heavies with a 1:10” twist. But those bullets are very long. Needed 3.6” plus in the mag to shoot 200gr plus Low drag bullets. Spent $700 on AICS bottom metal and three mags. Was running 3.715” AICS mags that only got me 3.48”. Tikka opened up the ejection port on the T3x to single feed 3.6” COAL but that didn’t do me any good. Re-barreled the action to 6.8 Western and not looking back. I will eventually sell off the bullets and brass, dies for the 300 win mag. I got most of the $700 back but still lost money. I have re-barrelled all of my Tikka long action cartridges to short actions. I also shaved some weight off of each rifle and all are below 8.5 lbs.
