Where the chart loses me is .223 Rem 8" twist T3 Mag then it lists a barrel length
then directly below that is this listing .223 Rem 12" twist but now where the other lists T3 Mag it says barrel length?

?
Is the .223 with the 8 inch twist this particular cartridge?
The .223 WSSM (Winchester Super Short Magnum) is a .224 caliber rifle cartridge created by Winchester and Browning based on a shortened version of the Winchester Short Magnum case.What is going on? All I want to know is what is a Tikka T3 twist rate?
Tikka T-3 ChartNow this chart says all the .223s are 8" twist? These charts are directly from Tikka!
