Thread: 243 Ackley. Project getting closer, experiences and advice welcomed

@zimmer Neck turning into the shoulder helps prevent donuts in an AI case.

My load for the last many years is Berger 105 VLD in front of some N560. Barrel is 23" and its pushing 3180. Barrel life is better than expected. getting close to 1000 rounds and the throat looks like it will do plenty more. There has been no drop off in accuracy or velocity and no change to seating depth. lapua brass is on the 9th cycle but Im ditching some now that are getting loose in the primer pocket. There is some temp sensitivity with N560, Iv got it in the balistic app as 1.2fps/deg IIRC.
When its rebarrel time I will defiantly stay with the cartridge, its a great all rounder. I think Id try RL23 or maybe 26.
