On second thought - I should probably pick up a fast twist .223. Domestic as well as mil-spec brass overflows the brass trash buckets on our rifle ranges.

Cheap brass - the RCMP who rents out range for qualifications and practice, NEVER picks or cleans up their brass. Only our civilian members do that - interesting - the police do seem rather, ahh - sloppy.
They use Fed Match in the .308's and Fed. brass in their M16's, MP4's or whatever, etc.
