Help design the NZHS Forum Wildcat - Part 2.5 - Caliber

[yerimaginaryM8]

I have been through the 7mm wildcat process I now have a 7mm saum shortened 200 thou. After a lot of dicking around I finally have it shooting really well. 162 amax's going 2800 -2850, The rear bearing surface of the bullet is not below the neck shoulder junction and the bullets can feed out of a model 7 mag and still reach the lands.





Taking an existing cartridge and changing the length/profile with a form die is not straight forward, it requires precise annealing, a decent form die, neck cutting/trimming, neck turning. Its a lot of work, and then there are unforeseen problems along the way. Such as case folds which I managed to overcome to an extent by changing the order of events...



I am happy enough with the rifle now, and I learned a lot but if I was starting again I don't know if I would bother. After the first couple of batches of brass forming it starts to wear thin, it's a lot of work.......

If you guys are serious (this seems to be dragging on and going nowhere) save yourselves a shitload of hassle and just Ackley improve something, or neck something up and ackley improve it.
