[QUOTE="lancetkenyon, post: 1425833, member: 68875"] When I start with new brass, usually it means new load development. I go right to a ladder test with it, watching for an accuracy node and velocity flat spot. But I definitely check to see how much my brass grows at the shoulder. Some only grow .002"-.005". But others can grow as much as .015". If it is fairly close, I continue to fully work up a load with the new brass, usually trying to stay on the low end of my node, but keep everything recorded. Then go on to seating depth testing, which will also affect speeds, as the more jump you have, the less pressure you get, meaning slightly reduced velocities. It usually only takes about 45-55 shots including long range verification of drops. Then load up 50-75 more of the virgin brass to use as my loads. I will also load up a few of the fired brass after FL sizing and bumping the shoulders back .001"-.002" and verify that velocity and accuracy are the same. After about 100-120 rounds down a new barrel, it will speed up some, usually 40-80+ fps. If accuracy has not changed, I load up the rest and shoot the virgin brass loads first, then all brass should be formed to your chamber, and ready to go. If I have speed up out of my accuracy mode, back off a few .1 grains to get back to where you want and load them up. [/QUOTE]
