Have 300 cases good or bad or the same as regular brass 204 22 hornet
Thanks

IMO there's nothing wrong or objectionable with nickel plated brass.

Bill r: This question gets banged around every couple of months on this forum and many others.
I use a lot of Nickel plated brass in many different calibers from 22 Hornet, 17 Remington, 222 Remington on up and through 308 Winchester, 280 Remington and 30/06.
I have never noticed even the slightest hint of trouble with my loading dies, Rifles, accuracy or brass life in any of the Nickel plated brass calibers I use and have used.
I use the Nickel plated brass in many of my duplicate calibers to keep the brass segregated to a particular Rifle.
I also like the looks of Nickel plated brass and its earier to find once ejected in the field!

I've used nickel brass in 45LC for several years, only lost a couple due to splitting. I loose more on the range than I've lost to splitting.

I only use a minimal flare on the case mouth, just barely enough to get a .452" cast bullet started.

I've had 500 rounds long enough that the nickel is getting thin on a few cases.

Use it in good health. I'm gonna buy more pretty soon.

bill r: Welcome! Aside from the "sparkle effect" of nickle-plated brass, they supposedly do not expand as much as brass only brass. Nickle coating being more brittle. Regards.
