I've also been using it since the first Iron Banner. The statement was on the ammo you pick up from the ammo box, not the magazine capacity. I get 26 + 10 in reserve without FS and 50 + 10 in reserve with it. However, I've seen players get 26 + 26 and 50 + 26 hence my edit at the end. Actually, it would be very helpful if you could go into PvP without Raid boots and pick up a Heavy ammo crate, then do the same with Raid Boots, both while using Field Scout and tell me the amount of ammo you get. If you get more using Heavy Ammo+ and Field Scout than with just Field Scout (meaning they stack) then I should edit the guide. Also, while Smart Drift Hammer can 3HKO, you need less headshots to do so with Aggressive Ballistics. Versus low Armor (HP ranges from 188 to 210) you need one headshot and two bodyshots, while Aggressive Ballistics can 3HKO with all bodyshots. Versus high Armor you need two headshots and one bodyshot, while with Aggressive Ballistics it can 3HKO with one headshot and two bodyshots. If you get Crowd Control, it becomes a 3HKO to the body versus all targets, negating the need for headshots entirely while Smart Drift still needs one headshot if the target has high Armor. I figured that, so long as you use Perfect Balance, it'd be stable enough that the extra 3HKO scenarios would outway the slightly higher Stability, plus you have higher Range. Higher Range plus a 3HKO anywhere to the body versus most players makes it very easy to 3HKO from pretty far away without needing much precision. Though, as I mentioned in the alternative builds edit, Smart Drift/CQB Ballistics and Smooth Ballistics are all better if you go with Field Scout as you'll be needing that Stability.
