I resurrected a chrono when I started loading 6.8 SPC last year. Most recipes have been 'home recipes' because most books only carried original 6.8 SPC loads and not the improved SPCII loads. Had one I used quite a bit in Australia in the 1990s and sat unused until last year.
Have an ultrasonic and jury still out. Have not noticed much improvement in brass cleaning over media tumbling. Just ordered a Thumbler for wet stainless media (3 weeks backorder)
