Brilliant customer service - Just received two new lock rings and loads of brass screws for my reloading dies free of charge from RCBS in the USA. My own brass screws that secure the lock ring into position had failed so the rings were spinning. I was quite happy to pay for the spares, but I sent an email to the USA asking where I could get them and I got a reply saying they would put them in the post without a quibble. Superb customer service. I certainly will be buying more RCBS in the future.
