Thread: 44-40 Reloading/Shooting

so...if we look at comparable cartridges,how do they get around issue???
if we take .22lr its a projectile thats skinnier in the bum section inside case....if that was applied to 44/40 it would serve two purposes...
#1 allow thick walled brass to be used,thus upping case life and potential safe loading
#2 no need for worry about crimp,the fat section of projectile wont push back into case mouth,light crimp entirely feasible with thick brass anyway.

so what would it take...and would gains be worth the mucking around to achieve it.....
re donor cases...I was wondering what more common rimmed round shared head size.....
