I cant say enough about the the 260 Rem and the 143 Hornady ELD-X. Out of my R700 with a 26" hart select 1:8 over 42.3gr of H4350 im going 2775 with a SD of 5.
Killed a 200 pound black bear this October with it, One shot, at 100 yards, full pass, ran about 15 yards then piled up dead.
Shot a 850 pound bull moose in mid October, one shot, double lung, lead pass though wile jacket got hung up on exiting skin. Took about 5 steps then fell on his face.
Last wekk I shot a 246 pound 8 point whitetail at 458 yards. Dialed 7.75 MOA up, no wind, DRT high shoulder, full pass. (first time in my life ive ever had a TRUE DRT. He just hit the ground on the spot)
This is the last hunting rifle I will own. 260 rem does it all. Being able to spot my shots and such a predictable trajectory, combined with very high SD bullets make this a winner all around for me.
