Looking for 25-20 brass. If you got let me know how much. Maybe we can work out a deal.

Easy to make from 32-20. Would I be correct that you do not want to make it yourself?

From reading on the net not so "easy" to make. But I will probably have to go that route to get sufficient quantities of it.

"Easy" is a relative term I suppose. Yes, I lost a few in the beginning. Once I got by the learning curve I have not lost any. Expect to lose a lot if you do not anneal. Wrinkling or denting the shoulder is the biggest problem.
Here is my process:
• Anneal the top half of the case.
• Check and make sure the case mouth is round and not damaged.
• Lube sparingly with Imperial wax.
• Using a 25-20 bullet seating die, reduce the neck. Slow and steady here.
• Full-length size without the expander rod/button. Again, slow and steady.
• Use the Lyman “M” die to expand the neck and slightly flare
Before using the Lyman, have your barrel handy to periodically test fit to make sure the shoulder is properly set back.
Once this brass has been fire-formed it gets neck sized only for the life of the shell since I'm not shooting with any other gun/barrel.
As with any re-forming process, it always helps to have a hefty press that is solidly mounted.
My apologies if I am "preaching to the choir" in regards to these steps.

OR, you can buy 25-20 brass on Gun Broker. There are currently several lots available.
