Marty,
Does it qualify for Master?

I am slightly confused by the pic with the calipers measuring the group size.... The digits say 0.969", but the 1" mark, and some distance past it, is clearly visible on the Vernier.... In addition, I measured the diameter of the "X" ring on my screen as 20mm, and the C-T-C distance as 21.5 mm.... Are you sure the calipers were zeroed before you used them to measure the group?.... Easy thing to forget.... The only reason I ask is because my calibrated eyeball told me that group was over 1", just by comparing it to the size of the "X" ring....

Marty,

David... two items:
1. I should have typed in Master instead of Expert my mistake in the post(memory lapse on my part). I did add you to the NUAH list in the appropriate class by the group and the location of the group on the target.
2. After seeing Bobs post I printed out your picture of the target and measured the bull which came out to 1.497"( which would equal 1" on the target). Then I measured the caliper opening which was 1.564" which means the group is larger than 1". Getting very close to the same results as Bob.
Please remeasure your group and post the results to the get this squared away.
Thank you.

Thanks for the double check guys! After waking this morning and seeing Bob's post, I measured a ruler with the calipers 5 times and got 4 different lengths. It appears that my cheepo calipers are done.

Thanks for clarifying David. I'm sure you'll make Master soon enough.
-
This is the reason I don't like using calipers in pictures. One can make them say whatever size you want. I prefer seeing rulers in the pics.
Good shooting David.

You may be right. No way a ruler can give a false reading.

David, thanks for checking.... it was still GREAT shooting, and you will indeed make Master soon....

Nice Shooting!!!
You might want to try putting a new battery in those calipers, I have a set that I thought were junk until I put a new battery in them and then they worked fine.
Apparently if your battery is low it can make them unreliable.

Too late... The garbage man has it now but good info for the next set :D

I purchased a dial caliper from HF that is very accurate despite it's $20 price. The vernier is off by about 40 thousandths but it gets the job done well. It surprised me how repeatedly it measures comparing it to calibrated mitutoyo that I use at work. Open it up all the way at first and clean it with a toothbrush and some clp. No need to worry about batteries ever again.
