I'm in the same boat as you are; I shoot the 208 Amax in three guns (no, I don't have any to sell, sorry). I have been told the 208 ELD-M is basically the same bullet. If you can't find the Amax, you might try the M not the ELD-x.
I would give the 208 ELDs a try in his gun if I were you, mainly because the Amax's are going to be non existent very soon.
If you need more Amax's shoot me a PM, I have at least one box, maybe two I can't remember..
Tried eld sucked ! I found some already and they are on there way , 700 of them I'm going to buy more from some guys on this site also I won't be running out lol . Thanks to some help from good people
