My Tikka T3x with 1:11 shoots both 180gr and 200gr Accubonds and Partitions very well.
Is the 1 in 10" twist on all 2021 T3X? The sportsman warehouse website still shows 1 in 11".Tikka T3X in 300 Win Mag is now 1 in 10" twist
Amen! 220 round noses have no problems with 12 twists if not even slower, vlds of that weight would be unlikely to work.Twist rate, and gyroscopic stability relate to the LENGTH of the projectile, not the MASS.
It's important to keep this in mind when considering copper 'mono's'.
Gyroscopic stability (SG) is important when it comes to getting the bullet to target, as that is what keeps the projectile from tumbling in flight. At lower altitude, in colder air, atmospherics can play a surprisingly big role as well.
SG can also be a factor in terminal performance, and will help ensure straight line penetration.
Here is a stability calculator for anyone interested in running their own numbers;

I have a few Tikka and don't shoot any of them enough.Phil,
Sorry I can't give you any help with an ammo recommendation. I own a T3x superlite myself and it is a great dinky little rifle in .243. Its so lite even in .243 it jumps a bit. I can't imagine the recoil in 300 Win. Mag. How are you taming that big old recoil?
Good advice...thanks...I have a Sako 85 Finnlight 300WM that runs the same 11 twist barrel as the Tikka. I tried reloading a good selection of 180gr class projectiles and couldn't get any of them to shoot.
Once I moved up to Berger 210 HVLDs groups tightened up to sub 0.5MOA and I have shot them out to 1km on targets with good results.
I also tried some 215gr hybrids and quickly got them shooting tight groups, but I expect in the 11 twist they are losing some of the BC.
Don't be afraid to try some heavier projectiles if you can get hold of them.
Also, I know a number of people running Tikka T3s in 300WM and 7mmRM that run two loads, a long range load that they load long and single feed and 'spook and shoot' load that is loaded to fit the magazine for shorter range shots when speed is of the essence and dialling isn't required.

Not sure, it my guess is that the 1-11" Tikka's were manufactured turned before the change. I ordered my 1-10" on 2/7/21 and I'm pretty sure the change was made right around that time...the guy at Euro Optic said that Tikka had recently made the change...Is the 1 in 10" twist on all 2021 T3X?
