Re: Need Die recomandations
I agree with Varmint Hunter.
My 6.5-.284 Redding competition Seater and bushing die produce ammo with .001" runout or less. Very good stuff. It is what Sinclair recommends when you ask them too.
Most likely, if your reamer was made for Lapua or Norma brass, then you can just run them into a neck sizer or over a neck turning mandrel just to make sure they have consistent neck tension. Running them over the mandrel is very easy, and you will have to do it anyway if your gun is a tight neck. You shouldn't have to FL size them at first unless the reamer was made for .284 Winchester brass.
If it's not far, it's boring.
