Thread: Another Trip to the Range

Must have been the day for it.

I have been scrabbling around trying to get use out of old stock and went to the range to see how things played out.

Had an old tubs of 2206h that i wanted to try against a newer one, one open for about 10 years and the other half that (i misplaced one in the shed and thought i had finished it before finding it again...).

I also wanted to see how things fared if I changed the brass from Hornady 223 to Mil 556 Ball K100's which had the projectiles pulled when they got on the naughty list.

23.0 gns of powder in each.



Layout is:

Old Powder 223 New Powder 223
Old Powder 556 New Powder 556

Chrono showed the following ave over the five shots

2895 v 2850
2760 v 2778

Happy with the results and will now need to do some more work ups but after reading extensively about using 556 brass, with comments that walls are genarally thicker and can raise pressure, the reduction on the velocities was not what i expected.

Bugger - guess i will have to do more tinkering...
