[QUOTE="boscodog, post: 1104202, member: 44198"] I’d like some help with a few questions - I had a 338/300 “edge built that I want to use as a hunting rifle so I made it a repeater, OAL is 3.830 to the lands. Using 300 grn bergers, seating the bullet .020th off the lands I have approximately .500 of bullet in the case and about .235 extra bullet bearing surface. I was told that seating a bullet with the least amount in the case and still having full neck bearing surface is best for accuracy, is this true? What if any are the advantages or dis-advantages? I also have another question - Will I be able to get the same speeds using less powder than a bullet that is seated further out? My thinking is that the pressure will be greater. Thank you, Tom [/QUOTE]
