I own and reload for 340WBY, which most would consider extreme.
Some others are 338wm, and the ones that are wildcats should'nt be.
338\08, 338-57, 338-06, 338 RUM, 338Edge, 338 Lapua, 338-378WBY, isn't there a 338 RCM?
I consider the 33's the most efficient caliber hot or not.
In the hot versions no animal on the face of the earth is safe
