I've bought a Ruger #1B in 22-250 with the view of re-barreling to 219 Don Wasp. I have the reamer, barrel and case forming and reloading dies.

I'd appreciate any tips and information anyone might be able to share on case forming for the 219 Don Wasp.
I'll be starting with 25-35 brass on this one.
Also any load data would be appreciated as well.

Regards,
David.
