Tucker, Have just swapped my BAR for the R 1 and am alarmed about your durability comment and wondered if you could expand on same.
Must say that I have only fired about 20 rds so far but its accuracy does not compare. The BAR at 100yds found all 5 rds in basic contact.
However the jury is out until I have tried some more makes of ammo.
The Winchester supreme groups very badly compared to the Federal Shok.
Incidentally its a 300WSW.
