LVR and pressure

    ....The Berger 95 Classic Hunter (CH) has a "Hunter HYBRID " ogive and is 1.069" long.  The 95 VLD has a "secant" ogive and is 1.113" long.  In MY barrel the CH "touch point" measured at 1.730" for a corresponding 2.197" COAL.  The VLD "touch point" measured at 1.726" for a corresponding 2.328" COAL.  The attached images show the differences in COAL for various bullets (Bgr 95 VLD & CH are 2nd & 3rd from left)  for a similar "touch point" of their ogives as indicated by the thicker line bisecting the high point of the ogive.
