Well, we got out to the range about 9:30 this morning and spent a while getting set up.  
I set the chrono up and checked all the connections etc.  Since I hadn't used it in a 3 years I brought 2 new batteries.
Well, sorry but it went T.U., so I was unable to chrono any loads.
After about 45 minutes of re-doing everything and firing test shots over it and getting crazy, broken, incoherent displays I gave up.
So we spent the rest of the day shooting everything we brought.
I had a blast shooting the gong at 225 yards with my BM M4gery and my friends M1A Scout, both with open sights.
We did a lot of handgun shooting and broke out the .308 precision rifles too.
So, now I'm tired, sunburnt, my shoulder is starting to get sore and I've got a stack of guns to clean...and I've got to pack up the chrono and send it to Texas

Bummer. I was looking forward to this, as I'm sure everyone else was too. Hope you get your chrony fixed for next time.
