[QUOTE="liltank, post: 444066, member: 13275"] First loading sets to chamber. Second loading neck size only. Third loading have to bump shoulders. This is where my accuracy starts to fall off. I even anneal at this point. Fourth and Fifth firings are about as much as I can get and they become unusable. I've been using RL17 and have been happy with it initially. It has worked great for my .308 Winny. I was going to try some slower powders such as Mag Pro and IMR 7828, but since decided to just go back to the Winny for now. It would be interesting to see what the new Superformance powder from Hodgdon will do w/ WSM cartridges. I figured if I can push a 185 Berger out of a 28" tube, I'm still good to 775yrds with a .308 for deer. I may play around with some lighter bullets w/ higher velocities and see if I can get an additional 20 or 30 yards. My current load is 60.0grns RL17 w/ Berger 210's. I get a 3/4 to 1/2 MOA for the first 2 or 3 firings, w/ 10fps avg in 10 shot string. A Std deviation of about 7. My current velocity is 2896 w/ a factory Savage 26" tube with a break installed. Initially it shows little signs of pressure, but as I shoot the pressure seems to go up. Tank [/QUOTE]
