My brothers gun and his problem is he has been trying to get the bullets to touch the lands, (bergers & amax's). He has tried just setting the bullet in the case and chambering the round to see if it will push into the case from being jammed into the lands and it still will not touch. His accuracy has been erratic and not great from a custom gun. (Got used) its a Remington action with a PacNor barrel in a 1-8 twist and Mcmillen stock. We do not have a gauge to measure how far he is away from the lands. Also the cases at the max overall length they are hard to chamber. Any ideas?
