Range results from yesterday - first sunny day in eons, so I took the afternoon off and practically had the range to myself. Trying to stay on post in regards to the 139 scenar that the OP asked about.
Round robin (4 shot groups, 2 shot salvos, alternating bullets each time, 200 yds) accuracy trail w/ US869 and a few 139/140 bullets. Squirrely/gusty winds noted. T = 48F. All Fed 215 and Norma 7mm reformed, neck sized, 75.o gr US869. 1:9" twist, 25" bbl
139 Scenar (SD @ -0.030") v = 3,005 fps / group = 1.45"
140 NAB (SD @ -0.020") v = 3,020 fps / group = 2.55"
140 A-Max (SD @ -0.055") v = 3,010 fps / group = 5"
The 139 scenar smoked the other two.
Worked up to 77.o gr for 3,095 fps for pressure, but not groups. Need to start hoarding those scenars.
Next step would be to try some RL-33 and Retumbo with the Scenars.
