7mm saw issues

[deadly0311]

Chambered a 7mm Saw barrel using WTO reamer and hs gauges. Everything headspaced off the gauges just fine. On to sizing brass, federal and Hornady 308 brass, Hornady 7mm saw dies Redding .312 bushing, the rounds won’t chamber. Anyone who has used this cartridge know what the issues may be? Sized brass doesn’t even begin to chanber and the die has been run all the way down to where the press cannot cam over

Start measuring. Figure out where they don't jive.

Neck too thick? 308 sized down can end up at .316-.319 when loaded with a bullet. See what the neck is for the reamer.

This. I had to neck turn all my brass from the redding dies but have had no issues from the hornady dies but I use a .311 bushing.
