I was able to borrow chronograph for 20 rounds...
With 19.3 grains of H110 the average velocity was 2396 fps and with 19.6 grains of H110 the average velocity was 2420 fps... The SD was 18.2 and 9.7...
I loaded some with 19.9 grains but didn't get chronograph them...
Almost forgot the barrel length is 16.5 inches...
