The results will be the same with an elk reguardless of it state (relaxed etc), so long as a setup is used with enough penetration at the target distance. I had a friend loose a whitetail last year with this shot using a 130 gr btip in 270 WSM failed to break the shoulder/spine or penetrate the chest cavity, he was using a borrowed rifle instead of the 338 Lapua/225 Accubond rifle I built him. This same rifle with different bullet selection would have been great, but the shot requires more bullet construction than a heart lung shot. Lets face it in the heart lung world even contacting a rib on both sides we are only talking 3-4" of solid material to penetrate to have a pass through with most of the chest cavity being air. You can perform that shot with almost anything, but going to the high shoulder just requires more. I really like the 300 gr SMK from the 338 EDGE or something similar in performance (Lapua, 338-378 etc) when taking this shot even at long distance it takes an "*** whippin with it". I have also taken this shot on elk with 338 Win / 250 Partition, 300 Ultra / 200 gr Accubond, 338 Edge / 300 gr SMK, and 7 mm rem mag / 160 gr Accubond at distances over 300 yards the results were exactly the same on all... instant *** whippin. Drop at the shot, no trailing, no second shots and no doubt about the hit. The people that usually turn a nose up at the shot location site meat damage as the reason. I cut and wrap my own as do alot of other people and I will gladly scrap a double hand full of meat for the effect of the shot, meat loss is minimal and 100 times better than a lost animal.
