That’s quite the jump. I know Tikkas have long freebores, but wow.

I had good single digit SDs and ES with H4350 at .030, hit a .263 moa with that jump, So I will start here and tune it if required.

Looking forward to your results of N555 vs H4350. What's your barrel length? I'm just starting the development of a load for an 18" barrel.

Looking forward to your results! Case is full?
I am on a R26 and R16 kick right now, so far my rifle likes both.
