Thread: Tikka T3x Lite in .30-06, questions about barrel length

I believe the speed reduction is closer to 25 to 30fps per inch .
And your suppressor might add 5 to 10fps , 30 fps might be a bit optimistic.

The 20” barrel will get you there if 600m is your goal, with right ammos projectiles and a dial up scope.( hornady precision hunter ammunition or 178 gr eldm or eldx projectiles )
But if you can get the 22.1/4” barrel , yep maybe that would be a bit better.
