I have been testing and shooting my Remington Slide Gun in 30.06 with no crimp on the bullet. I have put a lot of time in getting loads right and bullet seat depth just right for accuracy. Now I wonder if I should have put at least a little crimp in to hold the bullet in case of a sloppy feed that could push the bullet down the neck. Like I said I have put a lot of rounds through it with no problem but not in hunting conditions where I have been known to get a little excited and put a few live rounds in the bottom of the duck blind with my slide shotguns. A sloppy feed is not imposible but I think the bullets are fairly tight as they are. Anyone have any experience with this.
