I will not be hunting any game with the 212 ELDX's. They are accurate but not a killing bullet, IMO. I would be curious to see how you would do on elk with a 225. I'm not sure X or M. I am trying to develop a reload with different bullets but work has kept my range time way down this year.So I too am curious on the 300prc 212 ELD-X vs ELD-M. I am headed to Colorado in a few weeks and my Browning likes the 225 ELD-M better than the 212 ELD-X. Would I be safe to use the M on Elk or should I stick with the X? Or should I abort the whole ELD mission and go for another brand/type of bullet?
