If you are asking about the actual bullets and not loaded ammo, I've used some from several years back. Weight and size were bang on, the cannelure left a bit to desire if it was important to get a good crimp. It was very shallow, more of a ripple than an actual indent. I didn't have a problem in my 586 but always wondered if the crimp would hold in a lever-gun tube.
These were 158g from about 5 years ago, not sure if his current stock is the same.
