It should be noted that when reloading the weapon with a round still in the chamber, said round will be ejected onto the ground and can be recovered by being picked up. The rifle can contain a max of 5+1 rounds, but can only be loaded in the field up to 4+1. It is still possible to achieve 5+1 rounds while in-raid, but it requires you to unequip the rifle, remove the magazine, and load the extra round into the magazine via the inventory. The internal magazine functions similarly to the SKS's magazine, and using this strategy you can achieve 20+1 rounds with the SKS while in-raid.
