take this with a grain of salt. BUT I worked a load up using them at 100 cloverleaf groupings.Went to a club match this past weekend and need to true dope so did that friday. about every 10-15 rnds fired i would get a flyer, and NOT a little off target but at 600yards 14 inches off! SD were as good as honady brass can give 15's. these are 140 elds. the bergs shoot more consistant groups and if there is a flyer it is always me. Stan
ps i have 500 more of the elds so either i need to figure out or sell them!.
