[QUOTE="nralifer, post: 2719412, member: 94556"] Assuming the 338Rum cartridge is 2.760” long, the length of the ogive and bearing surface to the top edge of the copper relief band is about 1.027” for the 250 BD2 and 1.09” for the SBD2. So if you seat the bullet such that the completely covers the band the overall length should be 3.787” for the BD2 and 3.85”. The band is about 0.100” wide. Using either bullet the round will fit in an extended box with room to spare if the internal box length is around 3.95”. [/QUOTE]
