[QUOTE="RockyMtnMT, post: 1205670, member: 7999"] Okay, I am on the same page with you now. Makes sense. The only thing I want to add to your post is that when load it must be methodical. Have a method of one thing at a time from beginning to the end of development. There have been lots of discussions on what method is the best. I will not claim to know the best way. My way is to find a seating depth as long as is functional for the given rifle. Whether that is just off the lands or mag depth. In most cases it is mag depth so that the rifle will function as a repeater. Then I start working up the load watching velocity most but looking for pressure signs on brass. Also documenting velocity gains per grain of powder. If it does not look predictable I will stop there and change powder. To my way of thinking if velocity gains are unpredictable then it will not give good sd. Once I reach the target velocity I will load several to make sure that the velocity is consistent and take that data for an average velocity for later use. If at this point things look good I remove the Magnetospeed and shoot that load to zero and see how it groups. If the group is not acceptable I will then adjust seating depth shorter in .02" steps until the group gets better. Shooting a 2 or 3 shot group. If it does not group 2 there is no point in shooting another. If I can not get better groups with this then I may start over with different powder. This rarely happens. If I have to adjust seating depth to get the group to an acceptable level, I will then re check the velocity to make sure what it changed to and document that new velocity. Zero the rifle and shoot it for drops to the expected range of the rifle. This method will (with most rifles) give the best potential that the rifle has with that bullet. I will add that I avoid 100 yard work ups. Very little good data other than velocity can be gathered. I prefer 300 yard work ups. I am very much a KISS guy. (keep it simple stupid) Hope I did not take your thread in a different direction than you intended. Steve [/QUOTE]
