"Maybe".
I've had a couple of "Hornets" that due to "sloppy" chambers, shot better with full-length sized brass. This way, the cartridge "lays" in the chamber the same way every shot instead of being "forced" into an out of alignment orientation, different for each cartridge due to in-concentric cases from being fired in a a "buldged" chamber....
You'll just have to shoot and load for YOUR rifle to decide.
Good luck, I'm still "tinkering" with the Hornet after my first one in 1975......
36yrs and counting.....
