Title: Chrony test
Post by: Booger on January 17, 2015, 04:00:19 PM

I only shot my chrony once today, I always hit the back side of her. LOL

I ran 5 rifles through a chrony today. Temperature started at 50* and ended at 64*, it was fun but tiring. I only did 30 shots per rifle, 60 would have been over kill in ,my opinion. I was somewhat disappointed, but not really badly disappointed. I wish they were just a little more consistent. So here are the results:

 
TX200MK3   H&N FTT   Energy

It was a little windy for groups, but at 40 yards I hit 19 out of 20 1/2" squares and 4 of those were in the red dot bulls eye. If someone would PM me on how to post graphs I would post the .177 graph. :)

Those numbers a good. Anything less than 10.0 SD is good. *(&^ with the chrono that's some great shooting! ;D

I figured it out, here is a graph reflecting my chrony numbers.  ;)

Thanks for sharing that!
I have found that having a chronograph is a very helpful and informative tool. For me it's helpful to see what other people are getting for numbers. Even if it's not a gun I own, it may be a gun I'm thinking of getting.

How did you come up with the graph? Is it something you did on Microsoft Excel, or a program you have?

Microsoft Excel, I created other graphs, SD, AVG, High/Low and compared them which gave me a visual that numbers do not always compute in my small head eg. Lowest in one rifle vs highest number in another. :)
