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

I haven't sectioned a case for that reason but I might at some stage . The neck is .014 and the shoulder will be thicker again which is enough for me to take a few thou out of the junction with confidence. You can get the rifle throated so the bearing surface of the projectile is above the neck/shoulder junction in the case then any possible donut wont influence neck tension. To fire form I shoot the VLDs with a .020 jam anyway so I just use the same load. Accuracy can be very good . It wont be quite as good as something with a tangent ogive like a sierra gameking but a little initial stretch doesn't concern me, as long as the sizing die is set up correctly then any further stretch will be prevented.
This is a 6.5x284 case , I had donut issues with this as well. I use 40deg cutter for this.
