To be honest no...
I've not bothered compare it.. they do shoot pretty good.. I shot some Sunday at 1000yds at Bisley..
My rifle is zeroed in with a mod on with 162gr ELDX's and I shoot the ELDM's with a muzzle brake which was developed with the brake on. Approx 1.5 minutes different poi at 100yds, not sure on if it shoots the same poi line wise.. off the top of my head the poi at 1000yds was 0.5 minutes lower than the 180gr hybrids I used first.. the hybrids were probaly doing 100fps faster as I tried them on RS60. Something I tried innit 3 years out of intrest.. As the barrel has seen 2000 shots and I'm not so worried about barrel wear..
I entered the 180gr ELDM's 2nd BC value for is not the highest one..
Push to hard and they'll blow up..
I've had no blow ups in my 284 but I have using them in my saum.
Cost me serious points in a f class league match on 2 occasions so I stopped using them in competitive matches.
