    What reamer is everyone using (especially in a long action)? What throat length? What is the OAL of a 180 Berger VLD seated to the lands?

    I am thinking that a round loaded to 3.055" looks about right. There would be .285" of bearing surface in the neck. How much freebore would I need with a 1.5 degree lead?

    Thank you in advance for your help.

    Assemble a couple of 'dumby' rounds. Send them to your reamer maker. Then you'll know for sure!

    So how does this tell me what others are using?

    If you're willing to take "what others are using" especially off the web, ??????? When I'm doin' a "special", and as of late I'm doin' alot of 'um, I darn sure won't be using 'hear-say' for my reamer specks.
