Great speeds from a 20”. What barrel are you running?

Just a plain old Tikka

Did you reachamber a tikka barrel or put another brand (hardy, proof, etc) on it?

I just had a standard Tikka barrel rechambered.

Interesting what was the original barrel? I used a 7rem mag as donor for the action but got an Hardy barrel. I didn’t think the barrel twist of the original barrel was enough

Looking at your ladder velocities, which are quite variable with each step (some lower fps than previous step) it would pay to try a different primer. Otherwise you aren't going to get consistent velocity SD.
I always shoot a mid charge weight of 4-5 shots first to test the viability for the load combination. This will show if it's worth continuing with shooting the ladder.

What primer are you using?

These were shot with Fiocchi LR I do have federal 215 but when I did a test awhile ago the Fiocchi gave better SD over the 215 for a 5 shot group.
The ladder was just to give me an indication of pressure and looking for the flat spots I'm now going to load 5 of each 60, 60.2,60.4,60.6 and 60.8 and shoot a group of each.
