Title: Some chrony results
Post by: mtsheron70 on February 09, 2012, 05:30:46 PM
Here aree some chrony results.  Mainly playing with the Beta Master and the printer right now to get use to the functions.  But numbers are:

H&N FTT .22 caliber 14.66 grain:
Low velocity- 709.05
High velocity- 725.76
Avg. velocity- 718.46
Extreme spread- 16.71
Std. deviation- 6.08
Foot lbs. energy- 16.807

JSB Exact Jumbo Heavy .22 caliber 18.13 grain:
Low velocity- 654.39
High velocity- 662.59
Avg. velocity- 659.88
Extreme spread- 8.20
Std. deviation- 3.0
Foot lbs. energy- 17.534

JSB's seem more consistent from shot to shot.  Once I get my shooters bag I plan on grouping properly and posting those results.

Good numbers, especially for the 18 gr JSB's.
