IMHO; RWS are the only #11 that are consistent, hot or cold! In the late 70s a coworker gave me some Dixie hot caps to use, said they were "the" ones to use. Went out one a.m. about 10degs out, popped a cap before loading, dixie went ffft!! Dug out the good ol rws = POP!! Been using them ever since! Just bought 2 tins today!!
