[QUOTE="GLTaylor, post: 2053310, member: 111593"] Do you have any idea how far you are off of the lands? I see OAL listed as anywhere from 3.515 to 3.700, depending upon the bullet used. That's a bunch! Max charge for 4831 is listed as 73.0 grs, so I am surprised you are already somewhat compressed. I believe you definitely need a drop tube - but not sure you can gain 5 more grs of powder with it. That's also a bunch! I usually find where "0" is (touching the lands) and start seating depth testing at .020 off the lands. If I jump more, it is usually in at least 10 thousandths increments. For Bergers and other VLD designs it can be MUCH more. Same with Hammers, which are my favorite. They are very insensitive to seating depth. Edited to add: feeding is most important. Shorten cartridges until they feed flawlessly. Then re-work your loads from scratch. [/QUOTE]
