JJ, welcome to the forum. To the contrary, there are a good number of 340 Wby shooters here. For an accurate reply, which bullet and weight are you loading? I used the 225gr Nosler Partition with H1000 starting at load manual low end and working up for 340Wby. This load is used in heavy trees on elk and mule deer, not over 100 - 200 yards. Good luck
