OK,
Shot some loads yesterday...
RL17, 300 wsm, 208 gr AMAX loaded long, .010 off the lands, 24" barrel.
61, 61.5, 62, 62.5, 63, 63.5, 64, 64.5
61 & 61.5 seem to be a possible node on the targets and 63.5, 64, & 64.5 seem to be a node as well (based on the targets) BUT 64.5 had heavy bolt lift and I have questions about the other two loads on another thread as well. Velocities below are respective to each charge.
Average: (fps): 2,847 - 2,883 - 2,898 - 2,930 - 2,947 - 2,978 - 2,998 - 3,016
Extreme Spread (fps): 7.00 - 13.00 - 12.00 - 19.00 - 20.00 - 13.00 - 27.00 - 21.00
The first two groups centers were 1.4 & 1.3 below "center line" I drew on target, then group three's center line moves to .80 below center line. Group 4 (62.5 gr) goes back to 1.4 below center line.
Do I load up 61 & 61.5 again and include 59.5 and 59 to verify this is a node? Or would you just pick one of the two and work on seating depth?
