Planning a Colorado elk hunt this fall. I have used ML in Colorado several years ago. I have read alot of posts and it seems the BH209 powder is the way to go. I have a TC Hawken .50 1:48 or a New Frontier BearTooth Magnum 1:28 inline to decide on. My son will be shooting a CVA Optima .50. I am going to say we would probably not be shooting over 100 to 125 yards. I have killed 2 cows in the past both 50 yards or less. Neither dropped in there tracks but less than 75 yards. What bullets would you recommend.
