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.
The main thing to remember with this caliber, and any caliber formed from a larger caliber case, is to make sure the case neck thickness is no greater than the chamber will accomodate. Neck turning/reaming, if done properly, in addition to providing a safety factor, can greatly contribute to accuracy.
Have the gunsmith who installs your barrel make a chamber cast and use it to tailor the cases so as to give at least a couple of thousands neck clearance. Measuring a reamer is a tricky business, and a chamber cast, properly done, will give you the most reliable information
Stay away from any loads developed by Harvey Donaldson. He was a fine person, but he liked to load his cartridges up to the very maximum and beyond. The most accurate loads are less than maximum in any case, in my humble opinion.
I have a couple of Donaldson Wasps, neither of which has been shot in years. I guess I should dust them off and give them an outing.
