I do agree with the general sentiment of this thread.
After a full playthrough of NV, I used the campfire a grand total of one time... in the tutorial mission.
I used the workbench to occasionally make a repair kit.
It was a kick in the crotch when I took the Hand Loader perk assuming I would be able to make HP or AP ammo (or even incendiaries!)... nope, just got a couple of handload recipes. It was a second kick to the crotch when the .44 SWC load is broken (You need to take Hand Loader and get the recipe from a guy who makes a high Survival check. Well, we just established that Survival kinda svcks so I never got it that high.)
I was assuming that the reloading bench would be a great source to make lots of new ammo by looting casings off of bodies or containers and then assembling them with purchased primers or powder. Well the Gun Runners did sell powder jars and boxes of primers, occasionally. Never seemed to be sufficient, though.
Turns out that the bench isn't for making any new ammo. It's for breaking down ammo you already bought and then reassembling it into slightly better handloads. Except since the component requirements for the handloads use more powder than the base ammo, you end up with less ammo than you started with.
(By the way, it's bugged the same way that the Caravan cards are bugged; you have to remove them from your inventory and then put them back in for the jars to "break down" so you can use the components. That is, if you have a powder jar or primer box, drop it on the ground, then pick it back up. You'll get a Primers Added message.)
All in all for someone who anticipated spending most of their time at the reloading bench, it was a pretty significant disappointment. Maybe I just expected more.
For all the things NV did right, crafting's one of the things it dropped the ball on.
Once you figure it out (the UI is a mess) and get the Hand Loader perk the reloading bench can become your best friend. I use nothing but hand loaded .308 and .45-70s now. The key is understanding what breaks down into what you need. .308 is cheap and readily available and gives you all the components to make .45-70 hand loads except the cases which you can get by simply shooting off .45-70 HPs which are easy to get. Just last night I made 500+ of each with ease. Also, I have no problem with the fact that you can't breakdown ammo then get the exact number of special ammo by putting it back together. Obviously, just from game terms, that has to be some loss for upgrading to far better ammo. The loss is 20-30% depending on the round. You can actually make a large profit, even with that loss, from breaking down ammo and making the special variant of it. Personally, I just like to use to kill bad guys though.
Granted, the box and jar bug is a hassle but it isn't the end of the world. Hopefully it gets patched.
