I finally got to shoot some experimental stuff today.
Here's the criteria:
H&R 223, 1:9 BARREL
NOE 225 60 RN BULLET
GRAPHLOX LUBE
UNIQUE
SMALL RIFLE PRIMERS.
3 SHOTS PER CHARGE
50 YARDS.
TARGET DIAMONDS ARE 7/8" SQUARE
CHRONOGRAPH DATA
CRITERIA SAME AS ABOVE EXCEPT POWDER FOR FOLLOWING IS BULLSEYE.

CRITERIA:
LYMAN 225415 BULLET

CHRONOGRAPH DATA
Look at the 5.8 grain groups on the NOE 225 60 RN tests. The group size for the 5.8 grain charge in test number 2 is .240". The group size for the 5.8 grain charge in test number 3 is .333". In all the testing I've done, I've never seen two different bullets produce almost the exact same results with the same charge in different powders.
The group size for the 2.8 grain charge in test number 1 is .275".
Today's testing produced 3 sub MOA loads. I'm very pleased with these results.
CRITERIA:
LYMAN 225415
WC 820
The 4.8 grain charge in this test leads me to believe I'm approaching the proper burn pressure for 820. The next test will be 5.0 to 5.8 grains. I expect to find good results soon.
