[QUOTE="HoytemanPA, post: 335730, member: 286"] I don't have a short answer of the length to neck size. Just some observations from 10 years of LR loading. Full length sizing just bumping the shoulder is what I do for everything I load where accuracy matters. I use neck sizing dies in addition to FL dies in cases where a standard full length die with the expander ball removed does not provide enough neck tension on turned cases. At "some point" neck sized only cartridges need to have the shoulder bumped as they will get too hard to chamber. Not a good thing to have happen during a competition. Then when you do change this variable by periodically full length resizing, how can you be sure the load will perform the same as it did when it was neck sized only? Full length everytime removes one variable. Clean polished neck contacting surface, lots of neck tension, and bullets sitting in the lands have been a good rule of thumb for me. You can tell if you are doing everything right if you pull some bullets. Bullet pullers: Found the $20 RCBS press mounted with collets best after some preparation. First thing you have to do when you get a collet is run emery paper between the slots to break the sharp edges of the slots. Clean it with gun scrubber and then chuck up the bullet you will be using in a drill and hone it using JB bore paste. Clean it again and try it. If it leaves lines in the bullet do it some more. Now you have a bullet puller that you can actually use the bullets that you pulled.... for barrel foulers and first round sighters of course. Pull the bullets that you currently have loaded. If they look as they did in the box you are in good shape on your necks. If you can see where it has been seated in the case by digs and scratches, your necks aren't clean or smooth enough for consistent neck tension. I run a 7 wsm that has bullets that are held by 110 thou. I carry them in my shirt pocket while hunting. Lots of neck tension. I never could get the light neck tension to work well for me, ES is too high. Good luck. HPA [/QUOTE]
