I’m not surprised that it’s shooting well for you at that velocity, 2850-2950 seems to be the sweet spot for 105s in the BR variants. I’m with you, I’ll take 1/4 MOA over 100 FPS. I’ve got a 7 SAUM that prints 5 shot groups under .2” at 100 with a 168 at 2860 FPS. It’s well below the performance I could get but it shoots so well I just leave it alone.
