Strange how the 1:9 and 1:7 in johns 1st post bullet weight vs accuracy have similar results throughout yet the 1:8 seems to fluctuate much more.
The plotted numbers are the averages of a number of tests and a number of different rifles.

The results are from four 1:7 twist rifles, four 1:9 twist rifles but only one 1:8 twist rifle and only one 1:12 twist rifle. Apparently the 1:8 twist rifle wasn't particularly accurate.
Do you know about the TEXAS State Rifle Association?
