Shotguns have Rcl 1! Are they really recoilless?
No. Rcl 1 is used to represent the fact that all pellets leave the barrel at the same time, thus they have a spread pattern quite small compared to rifles in full-auto mode. IOW, it’s a number required to make shotguns behave the same way as IRL (more or less), not an indicator of true recoil. As you can see, most shotguns will have a ‘sum’ of 7-9 total Rcl (depending on the number of pellets) per shot (be careful with taking this sentence too literally, it’s an aid to understanding, not a textbook on game mechanics).
