Thanks, from your further explanation yep we are. I think that if you are careful in your load development, it doesn't matter where the pill is in relation to the lands - other factors can be more influential like tight carbon rings etc. I did read articles about load development where they do 'rough development' with the pill jammed and once at the velocity and basic group they want they then tune the load by adjusting seating depth deeper. In most cases this seems to slightly lower the pressure and adjust the harmonics. I find as we mentioned earlier that this is kinda a BS way to go for the average factory rifle - nice academic argument but in reality if the round won't fit in the mag it is really not much use for the majority of people's hunting use. Mental note - must try those subs again (my .308 sub load uses the 175gr Sub-X pill seated to cannelure, which has most of the pill in the case taking up volume and about a 6Km jump to the lands for 3-shots touching at 50m).
