Yes I have a M2 with a IC 555 that shoots lights out at 40 with Nitro # 7s ,I know some people will tell you that's to tight for nitros ,but in my rig its 180 and up . The Swarm threw very good numbers with the bigger, IE. H-13 #6 shot but only about 120 with the 7s .Great tube just didn't out perform my I C . Hope this helps .
