I need some opinions/advice. I am not trying to reinvent the wheel here. I am just looking for simple. I had pretty much made up my mind on a straight 7mm-300 win mag and had talked to Dave Kiff about the reamer. I was necking down some 300 win mag brass to seat some bullets to find the freebore I need. I got lazy and used my 7mm wsm sizer, as it already had a .313 bushing in it. I got it sized and a 180 vld seated. I assumed when I did this it would just size the neck down and leave the shoulder alone. What I got was a ~35 degree shoulder and a neck @ .313 with no visible donut. I, then, went ahead and put the .313 bushing in my 300 win mag dies and necked some cases down. This method leaves a donut on the outside of the neck/shoulder junction that I believe would have to be turned. I have the equipment I would just need a 7mm pilot. I really do not desire to turn though. At this point I am leaning towards the 35 degree shoulder and just sending Dave a couple dummy rounds. I would then neck all my brass down using the 7wsm dies and use these dies to bump the shoulder when needed. For all other sizing operations I would use the 300 win mag dies. I will be using 180 hybrids I just don't have any lying around right now.
