[QUOTE="Dmagna, post: 1895065, member: 106055"] Sometimes it does and sometimes it doesn’t. I have had an SD of 30 on a 5 shot group and my next powder charge with an increase of .3 gr will give me a 5 SD. Sometimes my loads no matter the charge will have 5 shot groups with an sd of less 10 and tiny groups. My 6mm creed did this to me, actually made it very hard to find a load because each test charge had a good SD and ES. So then I went to a seating depth test on the 3 fastest loads and found a good load from there. [/QUOTE]
