Got the Peterson .300 Win. Mag. Brass in and it is packaged excellently. Checked dimensions and they were all right where they should be. Weighed 50 cases and there was only .6grs variation in all 50, most were within a .4gr spread. No burrs, necks chamfered inside and out, flash holes drilled not punched and no Burrs. Primer pockets were really tight and barely touched them with the uniforming tool. So I Just loaded it and shot, worked up to my normal velocity and shot a group, sub 1/2”. They get a 10/10 for the product and the customer service from me.
