No dangerous game in my parts, so it's more about the want than a need.
I just like guns. I like cartridges. I like collecting and playing with both. Whether the target or game require it is trivial to the joy of having and shooting as many different gun/carrridge combinations as possible.
Which is the allure of the BFR.
I have Encores. I've never owned a BFR.
