I am going to hunt Dall Sheep with Max Schwab in 2009. I have a 264 win mag and a 300 win mag. I am pretty set on using the 264. I was wondering if anyone could give me some advice. Is a 130gr Barnes tsx enough, I will also use this for high country Mule deer and Blacktail here in Wa. Or should I use my 300? Thanks for any help.
