Re: Nickle vs. regular brass?
Nickle is certainly harder and more difficult to work with. That being said it can work fine. I was given a large lot of Federal nickel in 300 Wby. Given the cost, I reloaded it. Ensure the brass is very clean (I use stainless media), lube well when resizing and your dies will be fine. It will dull the case trimmer head quicker as it's harder, I replaced with a carbon cutter. You will notice some flaking of the nickel when trimming and chamfering, no big deal. All in it shoots fine, never corrodes, and feeds well. It's just a bit more difficult to work with. Would I buy it new, NO. If you have it use it!
As for capacity the federal is not coated on the interior.
