Does Gunsmithing allow you to create bullets made from special materials at 10% of the cost of buying bullets of the same type?

Mechanical Trap Minimum Cost
It doesn't look like you're pricing that trap correctly. Here's from the mechanical trap rules:
The base cost of a mechanical trap is 1,000 gp. Apply all the modifiers from Table: Cost Modifiers for Mechanical Traps for the various features you’ve added to the trap to get the modified base cost.
The final cost is equal to (modified base cost × Challenge Rating) + extra costs. The minimum cost for a mechanical trap is (CR × 100) gp.
And from the trap creation rules:
The base CR for a mechanical trap is 0. If your final CR is 0 or lower, add features until you get a CR of 1 or higher.
By the rules, you can't create a trap below CR 1, and the minimum cost is 100g.
Trap Math
Lets look at your costs compared to the rules. The base cost is 1000g.
It is location trigger (no cost)
Correct, this is no change to the base cost.
with repair as a reset (-200gp)
Correct.
there is no bypass
No modification to cost.
the search DC shouldn't be more than 20 (no cost), if not less (-100gp x (20-DC))
Correct, so a search DC of 15 would be a modifier of -500. Total of -700. You have no extra costs, as there's no alchemy involved.
Your cost is calculated as such:
The final cost is equal to (modified base cost × Challenge Rating) + extra costs. The minimum cost for a mechanical trap is (CR × 100) gp.
So you have (1000 - 700) x 1 + 0 = 300g. You could get it down to 100g if you lowered the save DC on the pit to 18 instead of the base 20.
Note that you currently have a CR 0 trap, and the rules require minimum CR of 1. You can get to 1 without increasing the cost by adding average damage (adding 7 average damage increases CR by 1). This would not increase the cost.
What if it really didn't have a cost?
If something really doesn't have a cost, you can make something up. For "digging a hole in the ground", the cost is time. The PCs can do it themselves, or they can hire someone. An untrained labourer costs 1sp per day.
The economy in 3.5 doesn't make a ton of sense, so you can assume the extra cost in a trap vs a hole in the ground is what's required to actually fool anybody into ever falling into it. It's best not to try to expect too much logical consistency on this stuff, becuase unless you use houserules, it doesn't exist.
How Long Does Digging a Hole Take?
Races of the Dragon p.98 has rules for using Profession (Miner) to mine, which you could also use for digging a big hole for your trap. The rules cover how long this would take based on how good a check you can make, with modifiers for different type of ground. You could combine those with the hireling cost to get an idea of what it'd cost to hire a bunch of people in town to dig a 10x10x10' hole.
(Summary version: a medium size miner can empty a 5' cube per day with a DC 15 check. DC 10 would do half of that, and every 5 you beat it over 15 lets you do another 5' cube. Large size works twice as fast, small half as fast. A second medium miner can assist and use aid another to boost the role, while smaller creatures can have more assistance.)
Now that you have your hole, you'd just have to figure out how to conceal it. There's no particular rule for that outside of the trap rules that I know of, but you could make something up.
You are using the table wrong.
The table assumes you have a magic item in mind and are trying to determine the cost. It is a not a table that you should be grabbing lines from to combine to form magic items.
That said, the entries:
- Single use, spell completion
- Single use, use-activated
- 50 charges, spell trigger
do not normally interact with (and if they do, they do not do a good job estimating actual price):
- Charges per day
- Charged (50 charges)
The first set are intended to price out single use or limited use items that eventually cease to exist or become inert like potions, scrolls, and wands.
The second set are there help determine costs for magic items that continue to exist forever until destroyed such as staffs and wondrous items.
Remember, the table is only there to estimate the cost of a magic item. It is not completely accurate and you should usually consult similar magic items for their price.
Best Answer
Yes.
Gunsmithing states:
Emphasis mine. That includes everything called bullet, such as Bullet, Adamantine Bullet, Pitted Bullet, or Silver Bullet. Note that these are listed as specific items, sometimes with different abilities than regular special material weapons. There seems to be no restriction on crafting other types of bullets though, and, being bullets, they are price-reduced as well.
A full list of Bullet pricing can was compiled by Nefreet on the paizo boards. It's noteworthy to say that this list was copied to the PFS Shared GM Prep Folder's GM's Guide to Gunslingers (and PFS is quite RAW by design).
