[QUOTE="Rhovee, post: 1332411, member: 101820"] I was shooting 3 shot groups to see what the average was. That's was just to see pressure and groups. I use a hornady automatic thrower and scale. Not to impressed with it. But do double check everything. I do anneal brass and use a neck bushing. Neck tension is 1 thou. I did find a es of 6 and sd of 3.4 in my 28 using Norma brass and N570. Still need to verify es over 10 shots, which I have loaded just haven't shot yet. I just don't have the time and space to run a 3-500 yard ladder. I have always loaded with doing seating first and then powder. But I did realize that there was a node between 3020-3040. This is for a new rifle and this time around I would like to find the node and stay there. I did shoot 63 for an average of 3174 and 63.5 for 3080. But 63.5 shot like garbage. 63.5 was 1/2". I was really surprised to see .5 grains change very little fps and close the groups by more than half. Seating depth was the same. [/QUOTE]
