All:I've got a problem with my new 6mm BR.The thing shoots like a house afire, but I'm concerned because I can't get bullets to slip into the fired cases. Looks as if it might be a case trimming problem, but the Lapua brass is very uniform at 1.540. SAAMI is no help, or possibly I'm not finding my way down their dark hallways, but bottom line is I haven't gotten a dimension. In another forum, the shooter says he trims to .550. I saw another soul who said something about 5.20. Seems awfully short. I realize that if I used any published figure, the problem might still remain. So---What to do? Only thing I've come up with so far, involves cutting the cases shorter until a bullet slips into the fired neck. But, I hate to start hacking into matched cases that are over a buck each, until I get some other info. If the other folks shooting this cartridge chime in, I'd sure listen. BTW: While my loads are modest, even then I'm getting absolutely no pressure signs. And the rifle has been shooting some loads into one small,ragged hole. Like it's been said: go figure. Bill
In theory, there's no difference between theory and practice. In practice, there is. My fate is not entirely in Gods hands, if I have a weapon in mine.
