Thread: Prepping new brass ?

If you do you might want to fire the primers and anneal the cases before your first load. Close to 50 years ago I had problems with neck cracks in Hornet cases in what I think were Winchester Super cases. You also might want to do some check weighing to help with your batching as Hornet cases have varied with weight over time.

If you do that, better to push them out. What with primer shortages no way I would waste them.

Lock and load I reckon!

Fwiw, I reckon @Oldbloke is on the money, push the primers out with a depriming die, there was a thread on this quite recently, well a wee while ago anyway. Very doable & the primers should be able to be reloaded if you aren't too heavy handed, softly softly catchee primer as it were. I loaded for a Hornet for a few years, gave it away as too much hassle but by neck annealing before firing them & then no more than neck sizing while reloading, you have a better chance of getting some case life from them.

Yes, that what I would do. Trim as well.

Cases are often a bit long (or short for that matter) from new. But there is a safety margin built in to the system. In this case you would get away with not bothering, but personally I would trim before loading.
