Thanks for all the tips guys. The Firing Line has always been the best source of info. I loaded up 500 230gr lead round nose in mixed brass with cci primers and 4.5 of bullseye. I was told this is six stages of 35 plates in each and they have to fall off the holders.
Practice has been a lot of fun. Its too bad so mmany anti-gunners hace no idea how FN awesome it feels to blast a wall of steel. Oh well more range time for us!!!!!!
