Look, Man,

I know you invented the first cutter and helical index,

....that "Rifled" the first barrel ever made,

....as well it's really plain that you've participated in most evolutions of rifle development since.

Not meaning to distract you from this noble and lonely objective,

.....could you explain to me the difference between "Rimfire",

and "Centerfire"....?

You're my hero , Lee

keep up the good wqork
