Reloader beat me to the punch... but I was going to suggest trying IMR 4064... I have had outstanding luck with it throughout the midrange of bullet weights in my .30-06. 150, 160, and especially 180 grain bullets loaded for boar hunting have performed GREAT for me using IMR 4064.
One thing I feel remiss without saying though is this. Get the loading manual(s) for the bullet(s) you intend to use, and use the data derived specifically for those particular bullets. IMHO, that takes a lot of trial and error out of developing a load. Be sure to look at the loading manual data which will tell you what cases, primers (pay particular attention whether the primers used were magnum or not) test barrel length etc. and you will have a really good bellwether for what performance to expect... By the way, if you are interested in a great little FREEWARE exterior ballistics program, let me know... I can either email you the .ZIP file, or you can download it directly from the site map on my website. (link in my signature) Dave
