Thanks for the comments.
I don’t understand the rationale of a soft followed by a solid given the performance of today’s monolithic bullets. I view them as expanding solids.
Also, if the soft is good for the first shot then why is it not good for subsequent shots?
I believe this is a holdover from days past. Most PH’s are not rifle nuts. If something works they do it again and again. However the world changes and improvements occur.
Lastly, well of course a 40+ will work but they do not obviate the requirement for great shot placement.
