my question is with c.o.l. Most manuals have anywhere from 2.92 for modern rifles to 3.15 for military guns. i bet i could go past that and still have room in the mag. My question is-Is it necessary to seat the bullet to the lands? i've read that it is not but would like the experts on here opinions. FWIW, i went out to 3.1 with room left. i'll be shooting these in a 1917 and 1925 m96.
