It is hard to imagine a reason that would cause me to buy a new production firearm when there are old production rifles available. Better fit and finish, big price difference, etc. Even if you get it refinished or you miss a small problem and have to have a gunsmith do a little work on it you are probably money ahead.
I think most of the new rifles are more accurate than the old ones, but I wouldn't buy a 30-30 for a target gun.
$0 of an NRA membership goes to legislative action or court battles. Not a dime. Only money contributed to the NRA-ILA or NRA-PVF.
Of course, you could just donate to the Second Amendment Foundation
I was feeling pretty good, then I looked around and realized I am not swimming or on fire.
