I picked up 200 6mm 103 ELD-X's to give them a go in my 6XC. I shot a few loads with RL17 on old shot too many times Norma brass.. So far just about everyone I have seen shoot the ELD-X's in a few different calibers have struggled to get them to shoot well as far as tight grouping at 200 yards me included. So I set a few up on resized Lapua 6.5 creed brass formed to XC .010 off the rifling and it did not shoot too well at all. So I set up on some old Norma XC brass same results so I went to .040 off and that seemed to work better so the best was about 3 shot 1 1/4" group at 200 yards at 3,180 FPS pushed up 3,250 FPS around 2" at 200 yards.. So I plan to load up the 3,180 load and see what we can hit at farther distance and I suspect it to work just fine but I will play some at further off say .060 or maybe a bit more.. Then it will be time to see if they perform on game mainly whitetail and some coyote.
