Nosler Model 21 in 6.5 PRC can't seat to lands. Freebore issue?

Both of those bullets like to jump. I jump my load .070. The Hybrid Ogive I've found on many of these bullets are very insensitive to the longer jumps. I shoot the 144 Berger and the 153 ATips but primarily have settled on the 144 Berger.
