Oooops. Bought the wrong cases

[Hotrod617]

I acquired a used F class gun several years ago and the bought a business. Needless to say no time for F class then. Fast forward to now, I'm retired and have the time. I was sure it was a 6.5x.284. Bought 4 boxes of Lapua for it. Got the gun out of the back of the safe and used the bore scope, everything looked great. Thought I'd check distance to lands as I already had a Hornady headspace/OAL case. Put a 6.5 Freedom Seed in it and proceeded to push it all the way out. Said to the stupid guy, not 6.5. Inspected the barrel for engraving and found .284 Winchester…
Now the question. Can I expand the neck and fire form the brass safely??? I'm 85% sure but with things that go bang I feel better at 99.9999%.

Yes, no problem. A few years back when Lapua had no .284 Win available, my friend simply used their 6.5x284 necked up for his custom .284 Win. This is a much smaller neck-up than 30-06 to .338-06 or 35 Whelen, or .308 Win to .358 Win, or 22-250 to 250 Savage, and folks do that successfully all the time.

Good luck with it,
