sticking the bullets around .010 into lands shouldnt move the bullets back into the case providing you have good neck tension,it will just engrave them a bit.as far presuure goes with sticking them into the lands,when i work up loads i usually start in the lands and work my my way back.i will start around .010 into the lands and use the ladder method,stepping up the powder until i see a sweet spot there[good velocities,low sd,and a degree of accuracy],while checking for pressure signs. once i find a good spot for the powder, i move the bullets back in .003 increments to find the sweet spot for seating.if i lose velocity when moving them back or lose the sweet spot on the powder i simply work back up using the ladder method again looking for that sweet spot.my-2-dave
