Sorry, I should have been a bit more clear. Jolder's Hammer carries 26 rounds per magazine plus you get an additional 13 rounds to use for a reload. A heavy weapon crate will give you 39 total rounds. JH can carry a maximum of 52 rounds. With Field Scout you get 75 total rounds. 50 of those are carried in one magazine. Your maximum ammo capacity will go from 52 to 150.
