Mike good job on the follow up.
I have had success and failures with the bergers. 300 rum with 210 on a 550 yard mule deer, lower shoulder ie heavy bone. Not where I wanted knowing the bergers limitations. Dropped right there, Never moved for 5 minutes, made a short walk to camp and came back to a "missing deer"
Another mule deer at 800+ with 7 rum 180 bergers, first shot again had the misfortune of hitting the shoulder knuckle. Thank God that deer stayed on it's feet so I followed it up with a correction that put the bullet on the high shoulder and toppled him.
both those hunts ended my use of those 2 particular rifle bullet combinations.
300 otms out of a 338 Lapua imp., much better results on 968 yard elk. first one on the heart, exit, expansion was ok, second one thru the classic high shoulder, great expansion 2-3" exit with a bang flop.
But that is the advantage of 300 grain pill, at least half of it should hold together, might change my mind next year if I am unlucky enough to have one land on the point of the shoulder. I may be knit picking not many bullets survive that hit very well, unless they are copper core.
