Yes you can push a 50 shot safely on a 420a so please don't post false information. A 75 shot can be handle safely but your pushing it on a stock to close to stock engine. Some say they've ran 100-125 shot safely but I doubt it would last that long. These engine's love nitrous just not a giant shot of it. A fully built 420a should be able to handle a lot more.

Chris if you would check out go-dsm from time to time you would see my threads of me discussing this.
