Neck up 225 Winchester

[wch]

Steps suggested to neck up 225 Winchester from 22 caliber to 6mm?

Dunno why not, J.D. Jones necked up .225 Win to 6mm, .257, 6.5, .270, and 7mm...and SSK still offers Contender barrels in all those calibers.

wch: Buy a 6mm expander from Noe or Sinclair and stick it in the neck and then remove. Gp

I run mine in a 6.5jdj size die with no problems.

I had a 6mm-225 in a Contender rifle barrel. Just ran the case thru the die, no problems.

Thanks to all who replied.

I have necked up hundreds of 223 cases to 7mm TCU over the years. The key is to lube the inside of the neck heavily. You might also find that the brand of brass makes a difference as well. It doesn't apply in your case but for me, the best 223 brass to expand was S&B so whenever I found a batch of used 223 S&B brass on the ground at the local shooting pit, that was me doing the "happy dance" (not a pretty sight). Federal and Winchester resized OK with few cracked necks but not as well as the S&B.

I have some Imperial sizing lube on hand- thanks for the advice.
