It is a 7-300win mag ai with .220 free bore.
Thanks, I appreciate it. I spoke to Dave Kiff at PTG recently about my own version of a 7-300 Improved. Sent him a first draft reamer print for comments. It uses a 37 deg shoulder, .007" less body taper, and .198 freebore. Left the short.240 neck alone. Think that's worth tweaking for a longer neck? I haven't heard of any real issues with it.
Am looking forward to what you may have done differently on your print.
