We didn't start to notice pressure signs until 25.7gr of BM2 with the 53 grainers, but obviously every rifle is different and we were loading a little longer than SAAMI spec, which reduces pressure a little bit. ADI lists 26.0 as max for 53gr, so we're in the same ballpark.
It also proved the Sako and Tikka barrels are very similar, if not the same (as you'd expect out of the same factory).
FYI, I also tested the 70gr Nosler RDFs and couldn't get them to shoot. 24.9gr of 2206H was starting to get hot, but had my best results with 22.8gr of BM2. Reloader 15 was OK, too, at around 24.8gr.
I have some 69gr Sierra Tipped Matchkings to try next - anyone got a good load for either the TMK or normal BTHP 69gr Matchkings?
