Going to Colorado on an elk hunt and I am planning on taking my 6.5 Creedmoor....am I crazy??

I have been shooting it along with my 7 Mag and 30-06 all summer...the Creedmoor just out-shoots the other 2 rifles. The Creedmoor shoots just as well at 250 yds as it does at 100 yds. In my head I have 2 voices: one telling me I am under gunned, and the other telling me that a well paced bullet will kill an animal every time.

I will be using Hornady Precision Hunter Ammo with the 143 grain ELD-X bullet and will limit my shots to 250 yds and under....what are your thoughts...am I crazy??


PS - I am starting to fade away from the big magnums I have shot in prior years...taking a beating and with decent accuracy is not fun anymore, LOL!!
