Increased case capacity, decreased velocity?

[QUOTE="Michael Eichele, post: 245747, member: 1007"] It is hard for me to say what I would do not being able to see the fired cases for pressure signs. I also dont know how close you are to the lands currently. If it were my rifle and there were NO pressure signs, I might SLOWLY work the bullets into the lands. It may be that simply moving them closer to the lands will get the 2900 mark due to the dramitic increase of pressure. PLEASE NOTE! This shuld be done slowly. Where ever the bullets are now, I would move them .010 closer to start and if ALL is well, I would move them another .010. So on and so forth. Also note that sometimes this can make a small pressure increase untill you get real close, then the pressure can really jump. If one were to work slowly up to the lands and still didnt have the desired velocity and pressure is still safe, then one could talk about adding more powder or even switching to a faster powder. When one starts to see pressure signs (ie: cratered primers, ejector marks, sticky exctraction ect....) Stopping and backing off 2 grains is a good idea. This will be a MAX load. At that point I would most likely be around the 2900+ mark. Hope that helps! Be carefull! [/QUOTE]
