There's news on the Lyvale Express 3" ers .
Apparently they've had a lot of complaints about the 53grm cartridge not re-cycling in many semi autos and as a consequence I believe they have now stopped making them . Instead they are doing a 50grm'er with crimp closure instead of the rolled on the 53grm . I'm not sure if the 47grm alternative has fallen by the waistside or not , maybe it has now as this new one covers all bases so to speak .
