I have had my edge now for 2 days and am loving it. Still breaking in the barrel and seeing where pressure signs start to show. With 300 bergers i have had it up to 94gr. of h1000 with no pressure. Set it up to be a carry rifle and with my NF on it its 11 lbs. Never shot a 338 ulta mag (would be plenty of
but the edge has more horse power and is as simple as necking up brass (pretty simple as wildcats go). I have also heard bad reviews of the 300 ultra nosler brass but all i can say is that its great. All weights came in within .5 of a grain and at 94.gr. still not showing pressure id say its some pretty tough stuff.
