Sorry to add to the thread hijack but... I have a Criterion 28" bull 260AI that's doing around 3100 with Berger 140 BT-LR and around 44 grains Rl17. No pressure signs, easy bolt opening, and 9.5 MOA come up at 600 yards. I've tied my best 600 yard league scores with this load but I'm worried about it burning the barrel fast so I don't use it much.
Thread jack complete, back to topic for me. Why choose Nosler over Lapua? I'm just curious, I've never tried Nosler brass.
