Re: bullet runout- question for 98 mauser/30-06
Anything over a 2-3 thou run out will open your groups. If the bullet doesn't enter straight, no matter custom or factory, you will not get consistent groups. Try turning your cartridge half way through the seating process 180 degrees. This old trick will sometimes help a factory basic seating die. Also, the Lee collet dies are inexpensive and load some pretty good ammo. Of course, the Redding Bench Rest dies are tops.
