This might not look like much, but I'd wager it's the best 100 yard sub group anyone's ever shot with 303 British bullets and Data Powder 68. :lol:

rebel, any idea how to post it over there?

My grueling load workup :roll: :
180 grain .311 Pro Hunter sized to .309.
2 @ 9 grains DP68: 660 fps
2 @ 10 grains: 743 fps
2 @ 11 grains: 804 fps
2 @ 12 grains: 882 fps
(QuickLoad way underestimated these...I was expecting to be super @ 12. Each two-shot string was 2-4 inches...not promising.)

Ran home and loaded 8 each at 13.5 and 14 grains but didn't have time to set up the chrono again. Shot two @ 13.5, didn't look like they'd group, so moved to the 14 which were loud so I assume they went super. Adjusted the scope, shot one of the 13.5's that looked okay, then five on the card.
