I have to admit that I have fallen prey to the fancy bullets out there and have been using Barnes TSX, Swift Sciroccos, A-Frames, Northfork Technologies, etc. bullets the last 10 years or so.
I have recently been working with an old firend that I had rebarreled as a 338 win mag. During break-in I was using Sierra 225 flat base Prohunter bullets available through Graf and Sons. My thought was to use these "cheaper" bullets for break-in and begning load development, but then to go to tougher "bullets" (read more expensive) bullets for hunting. Well these Sierras are shooting pretty darn well in this rifle and I thinking of using these to hunt with. With my 338 I am going to getting them going somewhere around 2750-2800 ft/sec. I'll use them to hunt deer on Kodiak (a 338 is more than enough for deer, but I think most folks know why I like carrying a heavier caliber on Kodiak), maybe moose (don't have anything particular planned this year yet), and Tadaa!!!!!! Delta Bison. Yep I am one of the very lucky to have pulled a bull permit.
So I'd like to hear from folks who have been using Sierra Prohunter and Gameking bullets. If you are willing tell me about penetration, expansion, etc.
