Re: Tikka T3 accuracy issue
I'm a bit surprised you are able to get over 1 moa from a tikka.
I'd dump the load and re-work it. It sounds like you are right on the edge of a stable load. I've had that a bit with lighter for caliber bullets, rather slow powder for the combination, or milder ignition. Easy to fix once all the variables come to light.
You don't say what your load is or the variables in shooting conditions.
