[QUOTE="Stannis Baratheon, post: 1819533, member: 109727"] Came here for info on neck tension, but figured that I would share some info as well. My 6.5-284 is a Savage 111 action with a 28" Criterion 1:8 bull contour. I just started load development on my 2nd barrel (both barrels are identical) and this one is going to shoot nothing but 150gr + projectiles (150SMK, 153 A-tip, 156 Berger). In my first barrel, I ran the ole trusty 4831sc/140VLD combo with Lapua brass. 52.0gr would get me right at 2900 fps, which is where that barrel shot the best (2880-2900). Tried to go faster, but ran into pressure signs before I could find another accuracy node. 2nd barrel, identical specs, I am starting with RL26 and the 150SMK. There is an accuracy and speed node right at 2900 again and I am working my way up to the next node, which I expect to be around 3025 fps +/-. I tested some of these in my first barrel right before I retired it and they shot well with no pressure signs to speak of. I am jumping the 150SMK .010" (CBTO = 2.480") I have always FL resized with a standard RCBS FL die with the expander ball (bumping shoulder back .002"). Like the OP, I am interested in switching to a bushing die to control the neck tension. I am not sure if this is going to be a worthwhile effort, or not, but I am going to find out! Thanks to Greyfox and all of the others for sharing their knowledge! [/QUOTE]
