STALKER GAMMA: Ammo Efficiency Analysis

Cheapest to buy, best to disassemble and all good craft conversion paths


Ammo crafting is around 90% efficient, meaning that for 10 bullets disassembled, you'll get, on average: 9 gunpowder, 9 casings and 9 bullet tips. The amount you get can vary widely though, so saying "by disassembling 2 boxes of this you can craft one box of that", while true on paper, might require more depending on your (bad) luck.
1. Ammo Prices by Trader

Ammo Box price per trader. Warsaw Pact (Loner, Bandits, Duty, Military, Monolith, Renegades), NATO (Clear Sky, Freedom, Mercenaries, UNISG), Butcher that you can find in Garbage, and the ruble equivalent of the vodka trades with Spirit in Yantar.

2. Best Disassemble → Craft Routes That Save Money

All the prices for these calculations are based on the REGULAR (white) price at traders you can see above. I was convinced there would be more, but that's it apparently.

3. Butcher & Spirit
Butcher (Garbage)
Butcher has great prices and should be used as much as you can if you have access to him. Unfortunately his prices are not so good that it makes sense to buy ammo from him for the only purpose of disassembling / crafting into something else. So buy it and shoot it, that's it.
Spirit (Yantar) Vodka trade → disassemble → craft target ammo

4. Good Crafts with Extra Loot

All the interesting ammo to craft when you have a ton of weaker rounds lying around.

📖
None of these crafts save money, every path below is a loss on paper. The point is turning ammo you looted and won't use into something more useful or powerful, at the smallest theoretical cost possible.
How to read the table
" 9x18 FMJ 45ACP HYDRA · 18% overpay"
Means 3 boxes of 9x18 FMJ can craft 1 box of 45ACP HYDRA, at 18% above its regular purchase price.
9x18 AP + 9x18 FMJ 5.7x28 SS190 · 35% overpay
Means 2 boxes of 9x18 AP AND 2 boxes of 9x18 FMJ can craft 1 box of 5.7x28 SS190, at 35% above its regular purchase price.
Only routes deemed "reasonable" are listed.

Crafts requiring more than 5 source boxes have been omitted. Most of those are high-end rifle AP paths (nonsense like 7× to 14× boxes to reach VPS or .338 Lapua)

All Assault Rifle and Rifle AP ammo overpay percentages are prohibitive, you're burning good ammo to craft marginally different good ammo at a steep loss.
