I just sent off my application for this year's (2010) deer & elk hunt in in Colorado. In the past, I've used my Weatherby Vanguard 30-06 and more recently my Weatherby 300 WSM. I've been successful with both calibers in harvesting bull elk and mule deer bucks. This year my hunting party is going to travel to southwestern Colorado where I'm told that longer shots are more typical due to the terrain. I'm seriously considering using my 270 Winchester (Weatherby of course) as I consider it to be my most accurate rifle, especially at long range. There's a Shepherd Scope mounted on top which I love. I'll be hunting both mule deer & elk as this is a combined hunt so 1 rifle for both. I was wondering if there were any of you out there that have taken elk using a 270? I'm considering a 150 gr partition and H-4350 powder. I also saw the 160 gr Partition available and wondered if anyone could give me any advice on the 2 bullets. How about it? Can anybody out there give me some advice ala Jack O'Connor?
