I have a .270, .300 win mag, 6.5x55 swedish, 16 guage pump and .50 cal muzzle loader. Except for the muzzle loader and the .300 they are all heirlooms so I couldn't see having to limit myself to 6 because of this. I know I only listed 5 long guns but my kids will inherit them.
Why should I restrict them from buying their favorite calibers just because they already have the legal limit? Case in point: In my instance I don't even use the shotgun or the .270 anymore but I won't get rid of them.
I'm sure glad we don't have that kind of silly (IMO) law here.
There aren't too many problems that can't be solved with either a quick mind or good aim.
