Question regarding barrel twist

[r.fallon]

Hi can anyone tell me what my tikka t3 in .223 has for barrel twist? I shot 3 different factory groups all 55gr. Win varmit, SB fmj and PMC FMJ. All of these shot 2 to 2.5 inches @ 100yd. Has anyone else had this before?

1-8 I believe

Either in 1-in-12 or 1-in-8. I have Tikka T3 .223's in both rates of twist. The 1-in-8 twist versions will have it stamped on the barrel.

(Either of them should shoot 55 gr bullets without stability issues).
