High SD is next to worthless if the constrution isn't up to the task at hand - witness the 300gr. .333's, 220gr. .308's and 160gr. .264's - yet, Harold Johnson's 450gr. solids for his Winchester (trimmed .5 steel core MG bullets) never once stayed inside a brown bear - and were only started at 1,850fps. They also never failed to floor a bear - some were legnthwise shots - so over 7' of penetration. Construction is vital and is necessary to 'humour' sectional density.
