225 ELDM accuracy issues

[WesternHntr]

I've been trying to get a good load together with 225 ELDM's in my 300 PRC and am having consistency issues..
I've played with seating depth, tried 5 different powders, and I still get 2-4" flyers at 200 yards.
I can't figure it out.. I'm getting really good accuracy with 215 Berger's.
Maybe my rifle just doesn't want to shoot them, has anyone had trouble getting the 225's to shoot

I always measure seating depth at the ogive if that's what you're asking

have you verified the stability with bergers stability calculator to ensure its stable with your barrel twist?
