Greetings Caberslash,
Have had very good results with projectiles seated well short of the lands, usually due to long throat and short magazine. If you can't feed the rounds from the mag then what is the point of having a repeater. I generally seat the projectiles 1 mm from the lands where the mag and seating depth allow but otherwise to suit the latter. The things that I find helps to get the best accuracy where the projectiles have some distance to go is to avoid boat tail projectiles and use the heavier projectiles, say 165 grains in the .308 W. A recent test series I shot in my .308 (long throated) with 125, 150 and 165 grain FB projectiles showed an increase in accuracy as the weight increased. All were reasonable for accuracy but the 150 grain boat tails I tried years ago were average at best.
Regards Grandpamac.
