6-284 back to 6.5-284

[nmkid]

Well, I believe it's time for a new build, as my present build is all but done. After many months of trying to get an acceptable load with my 6-284 I have given up the ghost. I have 400 6.5-284 cases I necked down to 6-284. What steps should I take to get them back to 6.5? Would I do this with expander mandrels? Annealing? Lapua cases, so I have some $$ tied up and a lot of the cases are still new.

If theyre not turned just run them thru an expander or just into your die if it has an expander

Uhhhhh. Well, they are turned. Now what?

 

[Dusty Stevens]

Theyre gonna get thin. Check em and see how thin once you expand. If it was me id get the right bushing and keep on moving til they get old

 

[nmkid]

Thanks. Guess I'll find out.

What loads did you try ? Velocity and twist rate.

Sorry for the delay, I was out of town. All told I tried 5 different bullets, 4 different primers and various powders. I'm over that rifle.

Sell those 6mm cases, start a new 6.5 w/ a fresh batch, don’t look back.
