Nothing yet, hopefully this fall yet but he’s a busy kid working and family affairs. With hunting seasons coming in, he’ll be busy with that too. I have high hopes for those 144gr Lapua bullets though, and well at least load up a ladder and check velocities and pressure in preparation for accuracy testing. I finished the rifle in time for his last evening match with friends and he dominated them quite handily…I believe it’ll be on the back burner until this spring@msalm, you get anymore testing or shooting in over the weekend with your nephew's new 260AI?
I've been going over the historical data for this barrel and even had one of the best F/open shooters go over my targets (and thankfully confirmed my own analysis) to figure out where I should load to. I'm going to shoot 44.8gr with the new lot of primers at 2805fps at the next 1000 yard club match to confirm my info. I really can't test too much anymore before Western States as I need to get a solid feel for this new velocity.
