Need to make a correction here. The BERGER Target and ELITE HUNTER Hybrid bullet are jump tolerant. That is why the .015 OFF THE LANDS is the starting point in bullet seating depth testing. From there you work back INTO the cartridge case in .005 increments . When you find a bullet seating depth accuracy node and you want to try to 'tweak" some more accuracy out. Go .002-to .003 to either side of that CBTO measurement. We normally do not have any information on barrel throat lengths. That can usually be gotten from the reamer manufacturer. However, in this case since I am working on getting an FT-R rifle barrel made I have found that generally most shooters using the 200.20x bullet will throat the barrel out .165 to .169 . If there was any misunderstanding in regards to jump tolerance of this bullet we apologize.
Take care,
What powder do you find works best Varget or N140 / N150 and why would someone choose N150 over N140?
