Thread: Tikka 6x45 / 6mm-223

Just a bit of an update .

I chornographed the 6x45 the other day .
The barrel had 95 rounds through it up to that point , so the last 5 rounds of the 100 cases I had loaded were tested for velocity .

edit - should mention the load

85gn Sierra hpbt
Starline brass
CCI 450
2206H 25.8gn

2865fps AV / SD of 11fps .

This load is basically the first one tried without any development or Fecking around . After 75 Rounds of shooting groups at 200m it is averaging 30.4mm / 200m = 0.522moa ( that average is all shots and includes the odd shot that was my fault etc that ruin an otherwise great group , shot in my paddock prone with Harris Bipod and Rear Bag )
It shows no signs of pressure and the primers etc are fine .
The powder weight of 25.8gn of 2206H is the max I can cram into the case , so have reached the limit of velocity with this load .
But to be honest this has exceeded my expectations and I'm very happy .
I will be playing with other Powders / Projectiles / seating depths but for now it's fun to shoot what I've got .
