Thread: Tikka T3 producing slooooow velocities

I own two Tikka T3s, a 260 and a 223.
I've been reloading for both of them and have always found it to shoot my reloads way slower than what other forum members are claiming.
I always put it down to the not enough powder, or different powder. I know that bunnies/goats/deer wont know the difference, but a few extra FPS never hurt anyone.

But today I shot with a mate who has a 20" AR15, heavy barrel 1:9" twist.
My Tikka being a 24" barrel shooting the same Hornday 55gr ammo, was 70fps on average slower out of my Tikka than his gun.
Now regardless of any variable that may have meant my 2800fps was actually 3100fps, I'm puzzled to my my barrel would be so much slower.

Anyone got an explanation, or a theory that could explain this.
The velocities we were getting were 2880fps from my Tikka, 2950fps from his AR.
