How many rounds are folks getting out of their AR Grendel bolts?

Mine is an AR Performance (not the heavy duty issue), I think mine's called the "superbolt".  So far I've got 20 rounds out of mine...and still going.[thumb]  This is not a gun that I expect to ever have a high round count on.  But I would like to know what to expect.

Thanks,
Jayhawk

Interested in this subject as well. I have the same bolt from ARP. Just started load development and have about 50 rounds on mine. Plan to put about 20 more on it tomorrow.

We have had one break since 2009 and that was because the receiver was not square. I have over 4000 rounds on one I use to test all the loads.

I have two Grendel bolts that i have used for my testing since 2009. I have over 7000 rounds that i have counted on one bolt and 300+ on the second. I have had no issues on either other than I have had to replace the ejector spring and also chose to change the extractor on the high round count one, that was completed approximately at 5000 rnds
