Bill,
Try our BERGER VLD bullet seating depth testing :
http://www.bergerbullets.com/vld-making-shoot/. be sure to use the HUNTING version. And see how bullet seating depth can affect cartridge case powder capacity, pressure, velocity and accuracy here:
http://www.bergerbullets.com/effect...coal-and-cartridge-base-to-ogive-cbto-part-1/ and
http://www.bergerbullets.com/effect...coal-and-cartridge-base-to-ogive-cbto-part-2/ . Any bullet seating depth testing should be done at the lowest powder charge listed for the bullet/powder/cartridge combination you are testing. Once the bullet seating depth accuracy node is found. Work the load back up slowly checking for pressure signs and accuracy until your highest velocity accuracy node is found. IF you find that after your bullet seating depth accuracy node is found. Try our 7mm 168gr CLASSIC HUNTER BULLET :
http://www.bergerbullets.com/new-berger-classic-bullets/. The 7mm 168gr VLD and 7mm 168gr CLASSIC HUNTER will use the same load data. In most cases with our Classic Hunter bullets your load development will consist of seating the bullet to the published magazine length (COAL) of the cartridge you are loading for. Then work the load up slowly checking for pressure signs and accuracy until your velocity accuracy node is found. If you have any questions please feel free to contact us at any time. Thanks for using our bullets Bill!
