As long as your reload and components can be purchased or made, no cartridge is ever dead. I get a lot of pleaure out of shooting my 256 Newton and no factory ammo or component case have been made for it by any major manufacturer since well before I was born. If my kids wish to do so, they'll likely be able to shoot the 1st Model Newt well into its 2nd Century.

PS - Ranco Loco is 100% on target, you really do have so much stupid in you, that you'll never use it up. Anybody who would willingly travel to Vermont to hunt for deer for other than the social aspect has got to have a screw loose somewhere. Other than traveling there to fish in the White River, visit the Ben & Jerry's ice cream plant in Waterbury for a cone, or to get a bowl of clam & mushroom soup at Colatina Exit in Bradford, I can't see much reason to visit VT, unless it was easier to get to somewhere in NH via I-91 than by taking the 2 lanes roads across the river.
