Seems like the 300 SMK is the favored bullet for antelope to elk sized animals when using the big 338's. A lot of the posts with pics show gigantic wound channels and bloodshot areas when using the 300 SMK. I am building a 338 impLM primarily for cow elk, doe antelope/deer for meat purposes. Will bullets like the lapua scenar and GS Customs SP that do not expand, get the job done with lung shots in the 200 - 1200 yd range? I recall goodgrouper phone book tested the scenar and found that it gave sporadic results on tumbling, but always penetrated --- wouldn't that type of energy put them down quickly enough with a lung or shoulder shot so that at most a short trail would need to be followed. To this point I have used accubonds in a fast 7mm wildcat and have really enjoyed the results as far as effectiveness in killing and very low meat damage even when hitting the shoulder, but want to use the higher BC bullets in the 338. Thanks for any input.
