Hopefully this is in the right forum
Your game has a life weight of 200-250 pound ( not a bear)
Your range is 100 yards( not critical)
Your rifle is chambered in 45-70 Govt.
Your choice is a 405 gr Rem FN or a 300 gr Rem HP loaded to arrive at the target with similar Energy.
Grouping is not a criteria.
Which would you pick?
Is there any difference in in the performance( expansion) of the various 300 gr HP?
