I will be travelling to Colorado for a DIY elk hunt in 2010, and am planning to take my lightweight LR hunting rifle because we will be doing a lot of hiking and need to be completly mobile. Normally I use this rifle on chamois in the alps here out to 600 yards with no problems. This will not be an intentional long range hunt, but I do want to hear from those who have experience with elk how effective I can expect the 7mm-08 to be at the longer ranges. I'd like to hope to get my bull with a close shot after a good stalk but conditions might force me into taking a long "only opportunity" shot, so I'd be willing to push the envelope a bit, say out to 500 yards. Is that asking too much of the round? I plan on shooting a 160 grain bullet, at the moment it's shooting .5MOA with 140gn Failsafes, but I think I'll will want more penetration from a heavier bullet on such a big animal. If anyone can suggest a good bullet that would be of some help, the Berger 168gn hunting bullet is appealing, just maybe the 180 will be a bit too much to get decent velocities. I have never had any problems with SMKs hunting with my heavier rifles, where I tend to use the heaviest for caliber weights but I would not feel comfortable using them with what seems to be a marginal caliber so I've left them out of the equation. Thanks.
