Bullet Sizing 308

[DueceMcGurk]

I can purchase 308 Winchester coated bullets in .311 diameter. Need .310 diameter for my rifle.

Any suggestions on how to size coated bullets and what sizer to use/make?

It's usually not a problem to use 0.311" bullets in a 0.310" groove diameter barrel.
Especially if they are cast bullets.

Agreed, you'll be fine.

My .310 already includes a .002 oversize for lead bullets. Can buy .311 cast. Want to shoot them at .310. Lee bullet sizers available in .309 and .311, no help. The bullets are coated so no need to lube them.

If those sizers are steel, I could hone a 0.309" out to 0.310" for you.

Randall,
I ordered the new design Lee breech lock bullet sizer in .309. If that is too small for my lead 308 load I will give you a call. As always, thanks for the support.
