I then put it through my.17AH full length die to get correct size on neck for bullet and also this double checks the shoulder so it will chamber.
I then anneal the brass and do a reduced load by 1grain of powder add a bullet and fire it... the case fireforms to the chamber and we have .17ah brass.... I can do 100 cases in about an hour and I get about 10 reloads from them.
I also reload the .17 grain bullets from kranks for fireforming an shoot bunnies/crows or just plink with them. at £5 a hunded fro the bullets I can reload cheaper than .17hmr ammo
What he said!
I do this for my 17 Hornet and also use the 17gr Vmax from HK but I load with my usual load and treat them as I do with completed rounds. Should perhaps mention one more stage. After forming the neck they need to be trimmed to length but slightly long to allow for the shoulder to blow out to the shape of the chamber which causes the overall length of the case to shrink slightly.
