[QUOTE="sacuster, post: 1079032, member: 90269"] I'm trying to develop a load for this rifle. All the books use a c.o.l. of 3.681", my rifle uses the CIP mags which allows me to run a col of 3.765", I'm currently loading to 3.750" because of feed issues. I'm using berger 300gr hybrids. I have measured to the lands by making a cartridge long and seating it a few thousandths at a time until the bolt drops with no resistance, the col is 3.894". So that gives me .144" jump to the lands from the mag and .213" jump from the book col to the lands. This seems extremely far to me, but I'm new to this. Any thoughts would be great. [/QUOTE]
