Finally got my chrony fixed. Shooting last weekend 82 yrds. here is what I got
200gr shockwave 100gr T7 1993,2032,2067 FPS about 1.5" MOA
200gr shockwave 148gr T7 2271,2335,2222 FPS about 5" MOA
The 100g value for a 200g SW predicted by the formular given by Zugunruhe here:
http://www.huntingnet.com/forum/tm.aspx?m=2577753
was 1984 fps, which is pretty close to the values shot by you. The median value of 2032 is only 48 fps off from what the formula MV = 2518.4* X ** .344, where X= powder charge in g/ bullet weight in grains. Interesting that the formula doesn't use ballistic coefficients or anything, just bullet weight and charge, but it is pretty close to what was shot with a high BC ML bullet.
