I did a OCW on a Tikka T3x today using H4350 and 140 eld-m. First hand loads for this rifle. What speeds/ charge weights are others getting using H4350 and 140s in the Tikka barrel?
My results are below ( 40.4 is goofy- oops). All input appreciated, Thank you.

I get mid-2600's using StaBall (and/or Acc4350) and Berger 140's before seeing pressure signs at the high-2600's. If you can get to the 2700's without pressure (heavy bolt, primer craters, etc.) ... that's pretty darn good. I like the node at 41.5.
 
My tikka superlite is getting up a bit above 2700 with the standard load of 41.5 gr. I guess I got a good barrel.
