[QUOTE="BillR, post: 653283, member: 462"] I was having a similar problem with my .25-06AI tight neck. Drove me nuts for a while. I finally moved up 1.5 grains in half grain increments and noticed two things. 1 the ES got smaller and 2 the soot ring went away. Not sure that is your problem but it took care of mine. I was using Retumbo powder which is considerably slower so you might not have to go up that much but it will also depend on where your pressure signs show up. Sometimes a faster powder helps too. I also do not like less than .0015 clearance per side either. If you get some soot build up it can actually make it too tight. I will also fire a couple shots through the gun just to get things settled in on a clean bore prior to shooting for group or over the chronograph. [/QUOTE]
