[QUOTE="RonS, post: 1056392, member: 68613"] I'd read that Retumbo was dirty but I haven't noticed it to be any worse than H1000. I'm running H1000 at this point because I had to settle on something and I didn't notice a lot of difference in accuracy once I found loads that were in tune with the harmonics of my rifle. I always single feed also so I don't worry about OAL. I always start at .020 off the lands as measured with the Hornady comparitor. Be aware that when measuring to the ogive the distance to the lands will be different for every bullet weight/type. Once I know the distance to the lands for the bullets I want to try I vary the bullets and powder charges (1 grain at a time for .338, .2 for something like .223) until something stands out as grouping better. Then I fine tune the load in .2 or .3 grain increments. Once I've got that dialed in I start playing with seating depth to see if it can be tuned further. In the case of the Lapua with the 300 SMK, I did not see a lot of difference when varying from .010 to the .080 range. If you decide that you want to go closer than .010 or jam them then you will want to start the load process over again starting at the bottom charge and working up while looking for pressure signs and grouping. Pressure spikes on the Lapua are nothing to be trifled with. My BVSS .223 with a 1-9 twist likes the Berger 73's jamed so I'm running -.005 on that load. The 6.5 Creedmoor with 140 grain Berger Hybrids I also left at a .020 jump.
