100gr 6mm Nosler Partitions were - are hard to come by the last few years, that's my .243 bullet of choice. The 6mm ELD-X and ELD-M shoot so good in my rifles that I hated to give up on them. But I can't get them to completely penetrate on deer or coyotes. The ELD-X is now my long range varmint round.
I've had the same experience with 103 ELD-X. Seems pretty fragile. About like the 105 AMAX. Things have died, but it wasn't ideal. I've had better experiences from cup & core 223 bullets on deer. They've all exited.
