Necking up?

[shoalwater]

I got tired of trying to find straight 284 Win brass, so I ordered 100 pieces of Nosler 6.5X284. Can I just run it through my FL 284 sizing die and be good to go? I've never messed with necking brass up or down. The die has just the standard decapping/expander rod in it. Thanks for the help.

It shouldn't be a problem, I just did the opposite in one pass on 100 rounds of white box new brass with no issues. Your necks will be a bit thin, but if you anneal them after the 3rd or 4th loading, you should be golden.

You will have no problems.
