I wish I could find reliable numbers by state but long guns have pretty spotty numbers in Michigan which is probably a good thing. I know there are lots here.
"These advances, typified by cartridges such as 8mm Lebel ( 1886 ), 7x57 Mauser, .303 British, and 7.62x54R made many smokeless powder rifles manufactured in the 1890s quite capable of accurate shooting at long distances. In fact, many antique smokeless powder cartridge guns from the 1890s can still compete satisfactorily in target shooting events alongside modern guns."
